chocolates becoming paisa's

In bangalore, after paying for the stuff which you bought from retail grocery shop, inturn you receive chocolates instead of 50ps, Rs.1, Rs.2 changes if he suppose to give you back.

I dont like eating chocolates so i tell them, i will get the change later. But when you ask them later, mostly they dont remember. Moreover my mama should not take chocolates since she is a diabetis patient. But this guys give that and make my mama to have it since it will be lying around home in more numbers.

I hate this sort of retail culture growing in bangalore...

Does this happening in your place as well?
