I used to serve at a restaurant where we wore pagers that buzzed us when a table's food was ready. Good idea right? Well the owners had the policy that you had to immediately go pick up the food no matter what, and that included if you were in the middle of taking another table's order. They said that people "understand" and are cool with it. Of course they weren't though. Every time I stopped taking a table's order and went and got the food, they were totally pissed off. I could not believe the owners did not understand why literally no other restaurant on the planet does it that way.
