and the customers. It’s not fair to them or to you to go in assuming negative things about the people you’ll be interacting with. You may end up enjoying the people you encounter on this job. That can end up making a huge difference in how fast that 5-hour shift goes.
I understand that this job is far from ideal for you but you have pretty much expressed that you don’t think you’ll like any job at this point. And it doesn’t seem like an option to just never work again.
I know you’re probably just anxious about change and that’s what’s behind you anticipating so much negative stuff about the people you’ll be dealing with., but try to remember that this can be a very short-term gig for you. Try to find your usually positive, upbeat personality and give this a fair chance.
And make sure you get some cute new clothes, deeply discounted, before you move on from this.
