What does adherence to fire code have anything to do with taking reservations? Also, reservations are free. It's not reasonable to expect restaurants to do anything and everything to honor 100% of reservations when many customers never show up for them and don't have any skin in the game anyway. Whatever point is trying to be made here is going out the window thanks to the "zero 9" nature of restaurant reservations. (Yes, not even 90% of restaurant reservations end up turning into actual paying tables.)
