You interrupt them
Another rude behavior is to interrupt them when they try to introduce themselves when taking your order. “I greet every table the same way. ‘Hi, how’s everyone my name is, etc.’ It takes maybe 5 seconds. I HATE when people don’t even let me get my name out with ‘I WANT WATER AND A BURGER.’ I’m going to be taking care of you for your meal; You don’t even care enough to know my name? Also, it’s just plain rude,” said Reddit user and waiter, photogenicusername.
