How bad this can be? will I be kicked out from my apartment?

hi all:

thanks for the answer at first. I just had an argument with property leasing office. the story is I moved into new apt in last Dec, but I didn't set up gas account under my name until this Jan(main reason was I was lazy....), so property management got the gas bill for Dec and paid it and then rebilled it to me, which is fine, I am willing to pay for that period(Dec), but on top of this property management(PM)also charges me additioanl $75 (called bill reprocessing fee), I disagreed paying this since it was just too much and I am not happy living here at all since my car got rubbed in the parking lot when I was out of the town(GPS got stollen and I spent a couple hundred dollor to repair the door and window, but no any action from PM). Now becuase I refuse to pay this $75, PM said they can and they will termnate lease and will send a letter to me later on, I am really wondering if it is really easy for them to kick me out from my apt given the fact that I do pay my monthly rental and any other utility bill on time. By the way they are a big aprtment management company and $75 is mentioned on the lease(but in a little ambiguity way).

Does anyone know the actual process of "kicking out" tenant? will the police come over? will they lock my door one day? do we have to go to court? is it easy for them to kick out tenant??
