An incident with Dominos delivery guy

So what happened was this - The delivery person came to the door and asked for whom the delivery was. I told my first name, he nodded approvingly, and handed me the order.

Then after, he saw my full name, and asked with a very disapproving look on his face, 'aap toh Brahman h chicken khaate hai' (It was a non-veg pizza). His face was illuminating such vibes of judgment against me, as if I am doing a crime.

Lol, why can't people just mind their own business.
