I was in Vegas recently walking through the corridor from the Encore to the Wynn. I saw a young lady, walking arm in arm with a distinguished gentleman. As they approached I took a quit look, didn't stare just a quickie. They were both smiling and enjoying each other's company. When I glanced I knew the girl. It was someone I had met on a couple of occasions, she is a very well reviewed girl here. We past and I kept on walking like nothing happened.  
Later that night I got a text from her, "Was that you I saw?" I said "yeah" and we talked alittle. The one thing she did was to thank me for not saying "Hi" or anything to show that I knew her. Of course that's like rule #1, discretion. I knew it, I wasn't going to put her in a situation where she had to explain who I am, although the guy would have figured it out.
Now Vegas being a small town guys are bound to see someone they know, or may see someone in an ad they saw...Hell I was once in an elevator with my date, and someone I knew happen to be in the same elevator with us..and not a word was said.
I guess we have to be discreet here, I know you're bound to see someone you know here or there and you might lose your senses but...be cool, don't be that guy.

Once upon a time I had seen a provider a few times. She was a dark haired, tall, size zero hottie. The sex was always over the top. She retired. Almost a year later, I was sitting inside my neighborhood Starbucks when she walked in pregnant. I wanted to say, “Hello”, but only nodded and smiled. She did the same and kept walking.

This sort of falls into the "don't eat spaghetti with your fingers" sort of tip.  As in, obvious.

Obvious, yeah you'd think it...But you'd be very surprised how many encounters these ladies get.

I lived outside of NYC at the time.   Work mostly in NYC and played mostly in NYC.        Did that NYC blind corner thing with a woman I knew.    We did say hello but we were both alone and startled 😮.     Now if I saw you Hpygolky!  I’d want an autograph 😂
