<human>: Can you provide a brief rundown of the text in within 3 sentences?

A little history- I work at a local bar where ownership has recently changed hands. Which in itself isnt terrible but so far things are certainly not on the up-and-up as they would have you to believe. One of the guys has been warned about his behaviour towards the female staff *long* before he became owner. In recent weeks he has made some offhand/sexual comments, as well as some .... light ...fondling? If you will.
The other night I worked I saw one of my two shifts for the following schedule were taken away, I inquired and was told "I dont know"  he came in later (already drunk) demanding I be the one serving him. After running up a $200 tab on booze alone, and being significantly wasted he said he knew why I didnt have that shift: "someone else needed the hours and the money, but dont worry I still want to take you home. And then we'll see about getting you some more shifts." Then proceeded to give me an extremely long hug as his hands slid down my waist to my ass and held on for about 10 seconds too long. A cutomer pulled me aside and said if that went on any longer he was going to punch bossman because it was inappropriate. 
Is legal action something I should persue, or because he was drunk it sort of makes the whole thing invalid?
<bot>: Bossman has touched/spoken to myself and other girls on staff sexually. Do I seek legal action (and how) or is the whole thing pointless because its a bar, and he was drunk?
