Pantaloons Fashion & Retail — Charged for carry bag

Address:

Crown Interiorz Mall Sector-35 Faridabad 121003

Today I shopped from Pantaloons for 7K. The cashier asked me if I wanted a bag which was obviously yes but I wasn't informed it's chargeable. As per my knowledge no retailer can charge us for paper bag. The bag isn't advertising Pantaloons but to charge for bag is not a part of any rule or policy. Either write it on counter that bag is chargeable so that we bring our own bag. When I saw the bill at home 7rs was charged. This isn't right at all.
