Waiting for your meal to arrive
One of the few mistakes that diners are unwilling to forgive is an exorbitant wait for their food at a restaurant.
We’ve all been the table that gets the short end of the steak — when dinner becomes a two-hour affair not because you’re enjoying the company but because something is going on behind the swinging double doors.
And when customers get hungry, we tend to get irritable and take it out on the server. But in reality you want to be on the same side as your server, because you both (ideally) have the same goal of getting food to your table in a timely fashion.
