It seems so many want to pay as little as possible. 
I can't tell you the number of times I hear ( in brasil saunas) some old guy with a 100k USD or Euro salary trying to negociate a discount from a poor boy who traveled 2 hours on a city bus to make some money selling ass or dick. 
Personally, I pay the asking price plus a small tip....or choose another that is in my budget.    The boys also have pride and deserve respect.....

From my experience there is no need to pre-plan anything - there are a lot of guys available for free and a small fee on Grindr. Having said that, I've made a few contacts on x.com that I would like to meet when I am in Manila next. I've never used a massage service, but I find the guys on x and Grindr are more to my taste.
When it comes to price I would always overpay, regardless of the agreed price. Even if you meet a young guy who isn't after money, a couple of thousand pesos can really help them out.
