This is definitely what can happen and of course most DJ's and successful club goer's have nights like this. This has happened to me plenty of times, the key is to shake it off as a bad night and not look deeper into it...This is a true story and is pretty much what happens to alot of people here while in clubs depite the difference in venue. If you're just not comfortable in that element then it's likely you wont' suceed. Stop making excuses why you can't do it and try something else that will work for you.
Usually I'll leave early at times like this, because the nights only get worst
