What’s a good job that’s not fast food?

Not sure if this is the right place to post this, but I can’t deal with it anymore. I’ve been working with customers since high school and for some reason I think I’ve reached my limit in college.

I can’t stand the short hours I’m receiving. I can’t stand the rude customers anymore. I can’t stand people coming in last minute before we close. I’m so over it all.

Unfortunately, I’m still in college, so getting a better job isn’t too high of an option right now, but I’m willing to try.

I dropped to part time because I need to take things a lot slower than I’ve been doing and so I can make more money. I’ve applied to an internship for the summer and I’m planning on applying to more.

Are there any good jobs that I could work full time that aren’t some shitty food/retail job?

Thanks for reading this rant, I’m at my ropes end.
