Consecionaria pitó chico

I've had so many things happen to me that in my situation and condition I have to conform with what I have and I found a place where it gives pleasure and satisfaction almost sexual to recount them. The day we went to buy a used car was one of the best. My wife looking at the car and the guy selling it was wanking off while looking at her without her realizing, but knowing that I would notice assuming he wouldn't do anything about it. What would you guys have done?
