To be VERY clear, I NEVER repeat with anyone who demands money before I'm DRESSED, let alone done.
I'm probably too much of a pussy to actually walk out if they demand money up front, but I'd sure want to. This has only happened to me once or twice.
I've had one or two demand money before I'm dressed, and I just find it disgusting. Let me wipe the fucking cum off my stomach before I'm fishing around in my wallet.
The fantasy is that it's not about the money, it's about the connection, and oh yeah, here's some cash. It's also decidedly ungentlemanly to handle money upfront - implies no trust in me.
The final point is that I haven't even picked an "option" yet. OK, OK, so I'm always going to take the top option, but don't fucking assume that.
