This thread is so pointless but what the fuck, here goes;
OP, is this your first job? You seem to think that hard work is optional, and it certainly is, if you have a bad work ethic or don't give a rat's ass about your job, getting hours, making money. If you think the team leads don't respect you it's probably because you have a shitty attitude and don't work hard. I already don't respect you and I just read your thread a few minutes ago. Hell, I don't even like you much as a human being since you seem to be a whiny, self entitled little twat.
Being cart attendant is not a glamorous job but if you'd applied yourself and not been such an insufferable cunt you could have cross trained on cashier, hardlines, whatever, and worked your way into a more air conditioned position. No need to "clap back" (whatever the hell that means) at your superiors, just prove that you're worth the money and effort but I'm sure you've proven to them that you're just not worth it.
If you think you're going to teach them a lesson by quitting or going postal, give it a go. It will be funny as fuck when you find out that no one cares. By the way, the majority of Americans do NOT want to "snap on their boss". Most of us have self control, a quality that you seem to be lacking. Seriously, is this your first ever job?
You might want to consider getting your GED. Expecting to be treated like a valuable member of the staff when you can't even spell *paid* is a bit presumptuous.
tl;dr
You're a dumbass.
