Bad bad service

We were having our last drinks when the Dj announced that no more drinks can be ordered. While we were finishing our drinks, the bouncer came and rudely told us to go outside immediately. We went our side and found a couple of white people outside. Immediately when they left, we were rudely chased out by a big black African looking man to leave the premises without finishing our drinks that we bought. That was rude, and unnecessary because we bought those drinks and cannot be chased out without finishing our drinks that we bought. Had there been take away cups offered it could have made sense. But for us to leave our drinks like that was wrong
