I've had clients arrive straight from work, on foot, so they have their briefcase/rucksack with them. No bother.
A couple of months ago in Harrogate I had a guy book a quickie. When he arrived he had a sports bag with him and when he put it down it went "clank". I said "What have you got in there?"
He says "Oh just some handcuffs and ropes, is bondage okay?"
Never mind I don't offer bondage and specifically say I'm dominant, but IN A QUICKIE?
I snapped "No that is not okay, I'll just pop your bag in the bathroom shall I?"
He came in about 5 mins through oral anyway, not sure what handcuffs would have added to the occasion
