What can I do after I was punched by a security guard?

Last night, on a Saturday, a couple of friends and I went to a bar and had a couple of drinks. We had a friend that was sober drive us to a strip club. When at the strip club, I didn't have cash to pay entrance so I told the person at the window if I could enter and pull out cash from the establishment. I was granted entrance, I was at the bar waiting to give them my card to get money. I wasn't getting attended to and was asking the cashier if he could just give me the money so I can pay the entrance fee. Out of nowhere, I got punched by a security guard and so did a few of my friends. We did not throw any punches back and grabbed our stuff and got kicked out.
