Funny story. One of the first times I went to Vegas my buddy and I had gone out to a club and when we were walking back through the casino afterwards a couple ladies approached us and started chatting with us. They were clearly prostitutes but my buddy had no clue and he is chatting with them and said something to the effect of “what brings you here tonight” and one of them said “we are working” and my buddy goes “oh, are you on break”. Haha
