Reliance Fresh

Hi..... I am regular customer of Reliance fresh. I purchase everything of household from this this store only . but i have little problem regarding the payment. First of all i want to say that 50 paisa means a lot . everytime when i make payment, the amount for eg. if bill amount is Rs 225.50, the billing person always takes Rs 226 ... they never take Rs 225. why everytime we have to pay that rounded amound of 50 paisa. they take 2 rs from us for carrybag and never leave 50 paisa. It's not fair why everytime i have to leave that 50 paisa, if that 50 paisa has no value then y they dont leave 50 paisa . the store manager should look after this matter . not alone me has this complaint everone says about this 50 paisa policy of this store.
