As Chick says, always take the money before bending over.
I was a kid back then and signed up for "Jose Canseco baseball camp". We payed money and Canseco was supposed to come and teach us how to play baseball.
His fagggot ass came rolling up in a limosine and he got out and just talked to some of his friends in the parking lot for about 10 minutes. Then he just left without even talking to us kids. He cancelled it just because he didn't feel like doing it, even though he was already there. And we never got out money refunded.
I still need to beat his ass for that.
