It was becoming a problem for me most of last year. My job was paying me weekly, and I was working near Plymouth Meeting, PA which apparently every agency tours their girls through. So it was as if I was at an buffet o'ladies of the night.
I could schedule a lunch session, and still get home at my normal time.
But I switched clients and luckily (for my bank account) I have slowed down to once every week or two. Mostly indy's, but I have a few AMPs I hit up every few weeks.
