Should I quit my restaurant job?

I agree-- I think you burned your bridges, justifiably got a reputation as a smart ***, and now it’s hard to get around that.

Find another part time job, and start off knowing that you have a lot to learn. Respect that they were in business before you showed up, and will remain in business long after you leave, and learn all you can.

Learning how to be a good employee is one of the best reasons to get a part time job as a kid. It’s a lesson that will serve you well in life.
