It cuts both ways. I can't be believe that some are so bitter about which practice is acceptable or not. I think the key comes down to research and communication between both parties before the date. Yes, I know there are times when little heads is doing the thinking with little time for research If that is the case, then big head has to at least be in control of the variables
I always try to put myself in the ladies position. That is why I simply put the donation down and let her make her choice on when to pick it up. I've had girls pick it up and count it in front of me. I've had girls who honestly didn't even notice the donation nor ask for it upon completion of the date. There have been a couple of times the lady asked for the money even before I had the chance to put it down. There has only be one time when the lady got lazy after getting paid. Actually, not lazy, but more into upsell mode. On those rare occasions when a lady's TCB skills were lacking was due to poor research on my part or at least I knew going in what the girl's rep was.
On the flip side, I think the girls should put themselves in a guy's position. Guys like to be in control-- especially when it comes to a business transaction. Demanding the money up front or grabbing it and counting it in front of us is an insult. It is a trust issue.
