I had a similar experience at DJ Station. I asked the guy i stayed overnight with in the morning if he "needed anything"? He said no and showed me his open wallet which was full of thousand baht notes and said his family owned many factories. I never take it for granted that every young guy in Bangkok is a money boy.
Even in Pattaya there are some guys with wealthy family connections so unless you are offing them from a bar or have made financial arrangements online it is good to use some tact if discussing their requirements for payment.
