I must quit my job...how?

So long story short, I'm a pool attendant at a hotel 17 been working all summer, my manager (well call her jess) hates me, no reason. She took me to admin and adressed the issue that I was swearing. Completely untrue I don't swear. I denied it. I went to the big boss and confronted him about it and basically said I didn't swear. He didn't believe a word, said he heard I wasn't doing my job, that I was angry all the time. It doesn't make sense I'm a bubbily person, I'm always cheery. I voulenteer at hospitals hold folks homes churches, working with kids. I gave him a list of people to chat with, and he basically just blew me off. Apart from this, I have a duity manager who could be my father easily, and he's very innapropriate. As in touches tickles and once tried to get me into the basement with him. The job always leaves me with a cold (indoor pool) and its very noisy (waterslide) I basically want out tomorrow. I talked to the big boss today earlier, and I don't eve want to be here. how do I do this in a polite way? What would you do in this situation? Thank you!
