Without trying to cause trouble I will say that I have heard from many SP that they don't care to see East Indian guys due to hygiene and roughness issues, among others. While this paints the entire group with a wide brush there must be enough of these types of problems if a number of SP say the same thing. If more than one EI has harmed an SP due to roughness I have no issue with them reducing their risks by refusing service to that group. I have also heard similar of middle eastern guys. It could be a cultural thing, over there they treat women like crap so not surprising many do it here. Yes, I'm sure there are respectful men from those areas but the few spoil it for the many, if it is just a few.
If one SP said this I would be inclined to think it was racist, but when many say the same I tend to think there's a trend. Just passing on what I've heard, don't shoot the messenger. I have a hard time believing I'm the only one to hear these sorts of things.
