India Shoppee Mart — carry bag charged wrongly

Address:

K g road nawada, Bhojpur, Bihar, 802301

I have purchased a some grocery thereafter they asked for extra charges of the carry bags Rs.13. Carry bags charges every customer but why because all carry bags on print him company name/brand name so company are also advertisement via customer so how can extra charges for the carry bags. Please look at that customer mental irritation.That's why i didn't take anything in Tarah bihar v mart mall.
