How do I deal with a coworker that compalined about me?

I think it's kind of ridiculous and petty on your co-worker's part that that they went to your boss over something trivial like a few crumbs. They could just as easily have talked about it with you face-to-face. Sometimes people complain over the littlest things - not sure why! If you want to say something to your co-worker I believe you have every right, and you can be polite so it doesn't offend them. Just tell them that 'I'm aware you spoke with our boss about me leaving crumbs on the desk, and I'm really sorry, and in the future feel free to come and talk to me about something and we'll work it out.'

Nope you can't say anything. They might tell on you again. Anyway, this is a professional environment not a social one. This person chose to go the professional route to solve their problem. Your expectations of them are irrelevant. This coworker owes you nothing. You can be as upset as you wanna be. Don't get personal at the workplace. Your feelings should be applied to friends and personal relationships you choose to have outside of work.

your coworker should of said something to you instead of the big boss. I would talk to your coworker and tell her next time she should say something to you

Apologize for leaving a mess to the coworker directly, then they might realize you didn't do it on purpose

We have a new girl who just started and she is ratting on EVERYONE to the boss about EVERYTHNG AND ANYTHING!! know no one likes her and avoids her at all costs. I think you should talk to the person first always. Maybe just make a lil comment about it , in a nice way . Like Oh sorry bout the lil mess i had, I thought i cleaned it all up.

No, do not do what these people say to 'apologize' to this person who just made you look bad to the boss. They are not someone you should butt-kiss. They might want you to be a little 'intimidated' by them (even though this person is a big wuss) since they have shown to you that if you do one thing that might tick them off, they will go straight to the boss. Well do a little bit of 'intimidating' back and confront the person, in small way. Just go up to them and say, "Hey, next time you have a problem, don't feel like there is a wall between you and me. You can just let me know before involving another person, and deal directly with me'. Don't say it in an overly pissed off tone like you are upset or anything, but don't do it in a meek and wussy way either. Go to them and assert to them that you pretty much won't take their bs off ratting on you about these petty things to the boss. This way, they will learn that if they do, well they will get a bit of grief and 'discomfort' in return when you go see them about it. Don't let them walk over you. Don't kiss their *** and show them that you agree with what they did. Otherwise, I would suggest COMPLETELY ignoring them. So as to give the appearance that their complaint was so useless you never even got wind of it. But from now on, don't be too nice from this person. Don't give someone more respect than the amount they give to you.

Couldn't happen here as most employers forbid eating at your desk. Eating and drinking at your desk (apart from a bottle of water) seems rather anti social
