Since we both stay in that area, you at Meredian and I Tarntawan...I'm sure we walk past there enough times to know who we want and if it's worth going in.
I'll do a foot massage with the one I like most first to test the waters, especially to see if they do a good massage. During the foot massage, we plan the full body oil massage details and tips, they usually start high, thinking a tourist won't know the rates or whatever, like asking 2k just for a blowjob plus the price of massage....I just laugh and then negotiate from there.
95% of the times the guy I like is willing to do extras.... the problem is getting them to come to my room instead, since my hotel is so close and they work so late, they don't want their friends seeing them walk into the alley 🤷♂️
