One of the local photographers has been plaguing me for all of my 6.5 years in Jomtien. Nice chap, always smiling, on two occasions helped him out against drunk farangs refusing to pay, and he knows I always donate 40-50 bt and a peck on the cheek to his flower-selling mother, without taking any flowers.
In the first month or two he had me at 60 bt a pop, and since then I have always sent him on his way when alone or with tart, but usually manage to get him some business at 100 bt a throw when I'm with friends...as I was yesterday, and took his camera, and took 3 photos of friends that are blissfully ignorant enough to get ripped off paying 100 bt per pic. All well and good, so far, except the 3 were all well out of it so I peeled off 200 baht which he squealingly repelled and demanded 300, nicely and with a smile, and repeated his demand even when it was spelled out that if that's what he really wants then that's he would get, but not another baht would flow to him or his mother from me or anyone I am with. Dumb. Pure dumb!
Over the years, just like anyone else who has been here a while, I have come across many examples of Thai inability to see further than the tip of their nose, but some still leave me shaking my head in wonder as to what if anything is running through their brain.
