Farangs Tour The Slum

The last two days I have been in the gym I have seen farang (white skinned Westerners) ride by and stop in from of the gym to take photos of Joh (the gyms female monkey, sort of a mascot that everyone loves). I was told that the farang are part of a tour, that a couple of enterprising Thai guides have set up. Their is one Thai person at the front on a bike and one at the back, with the farang all bunched up in the middle (for safety?) they stopped both times at the gym so the farang could take a quick photo of Joh. Not sure where else the guides take the farang but I guess the slum tour is a daily event. The locals take the touring tourist farang for granted and do not seem to get upset. To drive by on a bike stare at the poverty, the living conditions and then just cycle off seems wrong to me somehow (are the people of Klong Toey creatures in a zoo? a form of entertainment?), they should at least stop and spend time with the locals (talk if possible)and get to know a bit about their lives.
