Why should he? I wonder seriously why you even got involved in it other than having misplaced attempt on trying to help forum friend.
Immagine reverse situation : we are visiting bar together and boy on the stage, well known to you, is trying to attract my attention but for one of possible 84 reasons I chose to ignore those and I'm not interested in meeting him, at least not tonight.
Then he, knowing you, and fact we came together, is sending you message asking to find our from me why I did not engage with him. And if you did, what do you thing my response would be? Most polite I can think of is " I'm not sure what business of yours is in it?" but knowing myself for quite a few years I think it would be much, much more coarse".
Don't take it as attack on you, far from it, but I'm of VERY FIRM opinion that whatever opinions about boys and venues we share here shouldn't be passed down to them by other members. 12is12 voiced his displeasure and like everything in Vegas should stay in Vegas, not to be creating any waves as I said earlier.
Boy's decision could be rational I. E. client not for for his taste or not wishing to engage with any farang or whatever. It could be also irrational, feeling that tip is too small or slipping numbrt with it too weird ( by the way it's my preferred explanation) but I don't thing he owes explanation neither to Ignored client, even less to a third wheel.
Sorry but I must said all above as in the past I lost an access to very good guy due to misplaced attempt by well meaning friend to iron things between us.
