Exactly, I don't enjoy meeting other random punters, and when I do, I certainly don't look them right in the eye, or try and have banter. I keep my head down and try to be as discreet as possible. That old geezer was being a nobhead and breaking some of the unwritten rules of the hobby. I don't judge other punters I happen to meet, and I for damn sure won't accept being judged by other punters in return.
I can honestly say in hundreds of punts it's hardly ever happened:
i) bloke was going in before me in a sauna and was paying his £10 entry, he looked more embarassed than me
ii) bloke was coming out a brothel and had been kept at the door ages by a cow of a WG who thought it a huge liberty to unlock the door for him
iii) bloke was ejected from a brothel for being drunk and loudly had a go at me, telling me to not bother etc.
iv) teenagers shouting snarky comments when I was coming out of a Chinese place
What's probably happened is more is me being sighted going into 'known' premises by a fellow punter who smirks to himself.
