You did your job OP. Don't worry about what they say or think :)

Then they shouldn't have been shitty workers

Sorry to hear that OP. Unfortunately, people will believe what they want. Just keep doing what's right.

You did your job they didn't. They obviously need more training

Ignore them. You're there to work, not make friends. Sounds like they need to grow up and develop a stronger work ethic.

I hate the term "snitch," it's so stupid. I get not telling on people for petty things, but if you're doing something wrong, or giving bad service, expect that there's a possibility that you're going to get in shit for it. That is completely on you because you're the one doing the inappropriate action, it is not on the person that notifies an authority of your shitty behavior. Your coworkers are childish OP, this isn't your fault, it's theirs, maybe if they were better employees and actually did their job with courtesy, they wouldn't have gotten in trouble.

Sink or swim, if your coworkers aren't performing they shouldn't be there..

They spoke to the manger ? Your coworkers ought to have a beef with him.

You're paid to do your job there, not make friends

you did your job... so what
