A friend who worked in a crafts store said they dreaded when an Indian person would return a length of fabric, because it could not be resold even at a discount due to the cooking odors. But the manager would make them take it back and give the refund. She opined that some of them bought a long bolt of colorful cloth, used it as a tablecloth, and then returned it.
I can see that happening! Honestly, in my experience, Indian people were good to work with, honest but crafty in negotiating. So I didn’t want to denigrate them. Actually, it would have only taken one complaint to the Board of Realtors, claiming discrimination if a Realtor would have mentioned the cooking odors, they would have lost their license. But yet, it diminished the value of homes and we couldn’t discuss it with them..
