Should I snap at my partner for arguing with a delivery guy?
What did the delivery person do?
He's stupid, creepy, and has an ugly face.
It's not okay to be rude to people who are providing a service. You should apologize for your boyfriend and make sure you leave a good tip. you don't want a reputation as a disrespectful customer.
That sounds like a plan.
Service personnelle have a difficult job. A lot of our frustration is caused by situations totally out of their control. Arguing with them about things they have no power to change is unfair and a waste of time and energy.
