PVR Cinemas — No receipt for the food orders

Address:

PVR at Phoenix Market City, Bangalore

Yesterday(19th March 2022), I've visited here and ordered food at their café. The cashier was rude and didn't give me the receipt for the same and even after I insist on him to provide it. What is the problem in giving the receipt even though they charge a huge amount for a small cup of pop-corn. They're not paying GST, frauds at the higher level.

Their fake promise of "Consider your food is free if you don't get a bill". What the authorities are doing? And, why others are not escalating the issue?
