I’d like to speak to the manager!!!

I wanted to respond to the people who said, we should say our last seating is at 8:30 instead of we close at 8:30. 

We do not list our closing time.  People call and say what time do you close and we all respond we take our last reservation at 8:30.

And they still ask the question of will we have to eat in five minutes. 

I’ve never told anyone what time we close.  It’s always opened ended.  We take our last reservation at 8:00 tonight.  At 8:30 tonight.  At 8:45 tonight.

The closing part is inferred and you can ask any of my staff, I always say to their dismay, that you may take as long as you like to eat and enjoy your meal, you have be out by 1:00 a.m.

So we are already doing what you suggested.
