Discrimination issue?

I went to one of the shows of my favorite band and bought a ticket at the booth. As i reached the end of the waiting line to get in because i didn't have my id with me. See, i wouldn't be so upset if it wasn't for the following issues: 1) one of my two other male friends was permitted to go in without him having his id either. 2) I couldn't get a refine for my ticket because you have to present your id to purchase that ticket, yet i was neither asked or told of this at the booth. 3) I have only a visitor visa, so i don't legally get an id and on my driver license it says that it's not valid for identification. 4) Previously that show palace never carded and such information was never present anywhere. 5) in a process of us expressing out protest my male friend was called a "*****" and was shoved to provoke a fight by a bouncer. I don't know what i can do with this, but i'm just wondering if there's any law against any of these things and if i can somehow get a refund and an apology.
