Was I being chindi?
We are deciding where to get dinner and I'm treating, 4 family members including my brother. My brother recommends taj where per head comes easily to 5k per person and I say I don't want to pay that much for a meal. Then he goes on a temper tantrum calling me a chindi and that I'm not living my life correctly, etc.
I can afford it but I have always been frugal like that.

Your brother sounds like a pampered leach (no offence)
Has he ever made so much for dinner? If not he should not be demanding. Jo bolta hai woh hi hota hai
