Have any of you ever been in this situation?

Ok.. last night I organized a little 'Happy Hour' which I assumed would only be a couple of close friends. But as the night continued turned into a larger group then I had anticipated. All was fine until this one friend of mine brought a guy with her.. a guy who interviewed and NOT hired me a couple of months ago. I pretended I didn't know him and treated him like I would treat any other guest (glasses filled, tummies happy, everyone laughing, etc.) and he kept asking me where he could know me from because I 'looked familiar'.

Moving on.. he was there with some girl he was dating.. a 17 year old (he is in his mid thirties). The entire night I treated him as an esteemed guest even though all I wanted to shout out was that he was a moron for not hiring me and that he was a pervert for dating a child!!!! It took every ounce of self control I could muster. Has anyone else been in an awkward situation like this??? Tell me everything! lol (best answer 10 points!)
