Boomer at my bar

I am a bartender at a local dive bar and had a boomer man come in yesterday while I was working. He was rude from the start but it's my job to serve so that's what I do. I bring him a beer, I offer him a coozie to which he says very loudly "I'm no pussy!". Okay cool dude, it's not that big of a deal. Let your warm meaty hands warm up that beer. I help another customer and when I'm done I see his beer bottle upside down on my bar. Letting all the backwash and extras dribble everywhere. So I ask if he wants another and to please not do that. "Well I'm not paying just to look at you" was his response. Okayyyyyy here's your beer. It will be $3 more dollars. Then questions why the beer cost more today than it did on Thursday. Well we run a discount on Thursday that's why. He wants to see our policy? I'm trying to understand what he means and he says we should have it written down in a policy..okayyyy..it's on the wall what our specials are. I help another customer...turn around and his beer is upside down again. So I tell him he will not be getting anymore beer if he does it again. He proceeds to tell the guy next to him that "this barmaid is a fucking bitch." I take his beer and tell him to have a good day but he won't be drinking here. Everyone was happy when he left and I'm sure he went down the road to be a dick to the next "barmaid".
