I went shopping at Miniso at Commercial street Banaglore few days ago. I was asked to pay for the carry bag, I understand it is not a practice which is allowed. I was told cleary that i had to buy the bag. The products bought were big and i could not accomodate in my bag. I had to pay for the paper bag which they gave. The attitude was store manager was even worst.. where he said i could do what i wanted to but i had to pay Please help
