Not been offered to me by a prossie from AW or such like. I've heard some offer it after several meetings because they think it will keep you going back for more, I don't see the same one enough to get to that stage but I can believe it.
Has been offered back it the days of street punting, was quite common to be offered bb for an extra tenner if they were having a slow night. In every case it was a no and then faced the problem of getting the prossie out of the car, usually accompanied with a tirade of abuse. One did remove the condom when changing positions, finished off, pulled out and there was the condom on the drivers seat.
