I'm going to order takeout in bulk then tip a lower percent
Why would you give a low tip?
Because I'm annoyed at my ex- boyfriend Steven, I need to take out my frustrations on something.
Even if you're in a bad mood, it is very rude to under tip your server. They don't make much money and you need to give them what they are due. Try to keep your personal feelings and relationships out of service interactions.
Steven cheated on me with a bimbo and I want to get back at him.
Well, Steven has noting to do with the person who is providing service to you. You're punishing the wrong person. The server relies on tips to live.
