He insults those who make the food. He talks trash about the nasty food right in front of the poor, 3rd world vendor who just prepared it. He is not respectful of other cultures, but rather he uses those other cultures as a springboard for his show, all the while making funny faces during the actual eating. My momma taught me better, and I'd guess that most other Texans also know better than to dispaly such poor manners.
Thus, I categorize him in the column marked "Low class".
He is a showman, not a diplomat.
If you want someone that will wait till he's out of sight of the vendor to make fun of them watch Anthony Bordaine.
