LOL, they knew how big it was when they offered it. I had one woman tell me years ago, it's $75-150 extra depending on how big your dick is. Then she told me that I'd be 150. I laughed, thanked her for the compliment (which I'm sure she told everyone except the exceptionaly skinny), and passed. She dropped to 75, but I still passed.
Extra .80 isn't ridiculous considering it's cheap and fast place to begin with.
