You're only there for 2 weeks, you know you're only there for 2 weeks and everyone knows you're not going to get the terrible end of the stick unless they're specifically going out of their way.
I delivered a lot of different food in high school and it honestly was one of the worst jobs of my career, I'd much rather work in retail or clean pools. All of my income went into gas and repairing my car. If I got a tip it was a few bucks and back then we had the 30 minute delivery thing that caused so many drivers to get into wrecks I'm pretty sure it was eventually banned or made illegal (or they all just dropped it).
The car is provided by the restaurant, and it's large scale corporate customers so no tips.
I make enough money to survive, a chance to make people happy and get free food. I've been doing this for several months now.
It is a relaxing job when it's going well and not rushed. I like driving around aimlessly.
