I used to cocktail waitress at a nightclub in Vegas.
It was part of our job to mail in the post thank you notes.

I HATED it! HATED!!

After I sent one to a guest that I became friendly with.. I knew he was single.. However, I didn't know that he has his parents address as his address since he was in college.

His parents opened the letter.

I guess it's good that I give good head. But man, ohhhh man... I refused to send them after that.
