Callie is right. I'm almost certain the guy didn't out her on purpose--why would he? Esp. if he's a long-time satisfied client? It's complacency & comfort, pure and simple. We get used to things & this life-style and forget to THINK. There but for the grace of God go I... on either side of this one. I can see being the BONE-head who did it, unthinkingly in a second of idiocy after having had a few, or being the "outed" one. Good reminder.
Now, ladies: if I see you in public, and you see me in public, and I'm ALONE, I'd be delighted for you to come up & say hello. I don't know how you would feel about it. On the one hand, I don't want to be a hypocrite ("HE'S the kind of guy who'll put his dick in you, but won't say 'hello' in public!"), but on the other hand, certainly understand the need for discretion. There is bound to be some sort of etiquette for this that balances it out, but I'm afraid I don't know what it is. So... ladies? What's the right thing?
