Dealing with them at my old jobs were always a hassle. They never take no for an answer ever, they generally smell bad, don't have personal space, hard to understand, and it feels like courtesy is not in their culture. The women are usually not that much better either, and a lot of them don't have a good shape.
I try not to ever discriminate tho. Every now and then I meet one who was born and raised here and they usually balance it out. Two of my favorite coworkers were indian in the past and they were raised here.
Guyanese and trini Indians are way different as well
