Here, in Northern Thailand, I am contacted by a very good looking lad on Blued. All the photos look good, including naked ones.

He offers his services, but for 2000 short time, which is a bad start. I don't think there is any correlation between price and performance level. If there is, It's probably a negative correlation.
I say I don't pay 2000. After a short while, ignoring his request for 1500 as I am out walking, I say I can give him 1000 to 1200, but the next day.
So, the following morning he's asking what time are we going to meet and fairly quickly says "I can't wait all day for you to decide".
In Pattaya, I would reject him at this point, but the choice of lads meeting my criteria here is more limited. So after some thought, I say 13:00.
At 11:34, a farang who I have been chatting to tells me he is about to f*ck a very good looking lad and sends me his Grindr profile. Says the lad just arrived. So I check the Grindr profile and realise it's the lad I am due to see. The distance on Grindr all ties in, as the farang is living just around the corner and the boy is in the same location.
At 12:03, the lad is asking me if I am ready to see him. Two minutes later, the farang is on saying he had to kick the lad out (with 1000 baht)and describes his performance and attitude issues. I tell the farang that's the lad I am due to see, which surprises him. We discuss it a bit further.
So, after some thought, I cancel the lad. I had doubts over his attitude and this tipped the balance.
The lad then says I can't cancel as he already travelled across town just for me. A lie, obviously. I point out that he has been visiting someone nearby since 11:30, but without saying I was in contact with his customer.
Then, after a string of excuses, pretty much admitting non-performance in his other date, he says:
"YOU CAN'T CANCEL, AS I CANCELLED SOMEONE ELSE AT 13:00 FOR YOU"
Totally illogical, however you care to analyse it.
The lad keeps asking why, interspersed with insults.
After agreement with the farang, I tell the lad why I am pulling out.
Cue further insults and the lad gets blocked.
