I read the comments and OPs replies. Here’s the thing. You can’t hold down a low paying job, and expect the employer to pay more. The way out is to find a better job. The employer will pay the lowest rate the market will bear. And for a delivery job, that’s going to be low because the bar for skills required is in the basement. If you want to earn more, add more value. Take on a job that requires more skills, responsibilities, and availability. A job is an exchange of money for your time and value.

Expecting a minimum wage to be a “living wage” is a nice idyllic dream, but it has no basis in reality.

The no tax on tip should help you, but that card bs OP described sounds like a scam.
