Just to let you know...
If you're that group coming in 10 minutes before a restaurant closes, EVERYONE hates you.
No, but seriously. When it's completely empty and you come in, the kitchen has to wait for you to order, the staff has to wait for you to eat in order to clean and go home, and the bussers can't get tipped out until you pay and the servers can do their checkouts.
I don't care if you'll be "really quick" or "know exactly what you're ordering."
Everyone STILL hates you.
