Running late: what to do, and what happens if you do not call

If you’re going to be late for a restaurant reservation, call or text immediately, give a clear ETA, and use these exact sentences and a short checklist to avoid losing your table—or accept the trade-offs if you don’t call.

First thing to do right now

Call or text the restaurant the moment you know you’ll be late. Use the reservation platform (OpenTable, Resy, the restaurant’s number) if it lets you change the time. Don’t guess—give an accurate ETA. If you can’t reach the restaurant, show up and speak to the host on arrival. If you are sick, contact a medical professional for advice before dining out.

Exactly what to say — phone and text scripts

Use these short, specific lines. Pick one and stick to your ETA.

Phone (short): “Hi, this is Sarah; I have a 7:00 reservation under ‘Mason.’ I’m running about 20 minutes late—can you hold the table until 7:20?”
Phone (group/family): “Hi, reservation for 8 under ‘Lopez,’ we’re delayed—party might be two arriving in 10 and the rest in 25; can you hold two seats at the table?”
Text (if available): “Reservation for 6pm under Park — stuck in traffic, arriving 6:25. Can you hold the table?”
Allergy/food-safety add-on: “I have a celiac allergy—can you tell me if the fryer or prep line is shared?”
If you need to cancel or change: “We can’t make it tonight—can I cancel without charge? I reserved with a card under Kelly.”

On arrival: what to say, and what to expect back

When you walk in, go straight to the host station and say the same thing you said by phone or text: name, reservation time, and ETA. Be calm and brief. Example: “Reservation for 7 under Nguyen; I called—running 15 minutes late.”

Good responses sound like:

“No problem—we’ll hold your table until 7:15; if anything changes I’ll call.”
“We gave your table to another party, but we can seat you at the bar in 10 minutes or put you on the waitlist.”
“We need to charge the deposit because you booked a private room; do you want to keep the slot?”

Bad responses sound like:

“We gave your table away and we can’t fit you.”
“We already charged your card for a no-show.” (This is a policy outcome, not always a hostile statement.)

What happens if you don’t call

Restaurants react based on demand and policy. Common consequences of not calling:

Your table can be given away to a waiting guest—especially on busy nights. Hosts will sell covers when the floor is full.
If you paid a deposit or provided a card for a guaranteed reservation, the restaurant may keep the deposit or charge a no-show fee per their stated policy.
Smaller or low-demand places are likelier to wait longer; high-demand or limited-seating restaurants will reassign quickly.
Repeated no-shows can lead restaurants to refuse future bookings or require prepayment.

Those are trade-offs: restaurants must balance keeping a table idle for your grace period versus seating another paying customer. If you don’t call, you accept that the restaurant will optimize for covers and may prioritize other guests.

How restaurants decide—trade-offs you should know

Decisions depend on time of night, party size, reservations policy and floor plan. Important factors:

Time of night: During peak seating (dinner rush, weekend brunch) hosts have limited slack and will reassign tables faster.
Party size: Large parties use more seats and are harder to re-create quickly, so venues may be stricter about holding them.
Deposit or guaranteed booking: If you gave a card, the restaurant can charge per its terms; that secures you a longer hold.
Bar and waitlist options: If the bar is open, hosts often offer bar seating or a shorter wait for a smaller table.

It depends: a busy corner bistro might hold a table 5–10 minutes, a full-service fine-dining spot might hold longer if you prepaid, and a casual café may automatically give the table to walk-ins. If you need a guaranteed outcome, prepay or call ahead.

Quick checklist to act on immediately (and scripts to use)

Call or text now. Script: “This is [Name], reservation for [time] under [Last name]. ETA [minutes].”
If you have a card on file, confirm whether you will be charged: “Is my reservation guaranteed with a card, and will I be charged if we can’t make it?”
If you’re in a group, designate a point person who will give an accurate ETA.
Ask for alternatives: “If you can’t hold the table, can we be seated at the bar or put on the waitlist?”
If you arrive late, tell the host you called and repeat your ETA; if they’ve given the table away, ask politely for any available options.
If you must cancel, do it through the same channel you reserved (app, phone). Script: “I need to cancel our reservation for tonight.”
For allergies or medical needs, ask a direct question: “I have a celiac allergy—can you confirm whether the fryer or any prep surfaces are shared?”

Final practical notes

Calling is the single action that changes the outcome most often. If you can’t get through by phone, show up and speak to the host—being present often beats waiting quietly in your car. Expect different answers depending on demand and booking guarantees; when in doubt, offer to prepay to secure the table. If you have medical questions related to dining, please consult a healthcare professional.
