I've always noticed that with Asians as well, not just South Asians, but pretty much all of them. When my mom lived in an apartment building and she was taking the dog on the elevator they'd either leave and get the next lift, or wouldn't get on if the dog was there (this is a little ball of fluff).
I walked downtown one evening to go to the bank machine and an Asian man (Japanese) and his daughter came in. I had my two dogs (medium sized dogs) with me, they were sitting right beside me and I had them on the leash. They both had a terrified look on their faces. I made sure they knew they were leashed, but it didn't matter, they would not do their banking until I left the area, even though there was three other ABM's available.
I always thought it was because in their home countries they ate dogs, and are now terrified of revenge!! lol
P.S. As for the chicken thing - that is just something I CANNOT wrap my head around!! A chicken??????????
