If the change is not coins, but candy...

that kind of scenario happened to me when i went to the grocery.the cashier ran out of coins to give as my change,instead she gave me a candy i blurted out ahead of her that i will not accept the candy as my change and that i demand for my change.it's not my problem anymore if she ran out of coins for change,the thing here is i am a good paying customer and i deserve the right to have the change equivalent to the amount of money i paid for my items and that a customer is always right if he/she demanded a change.

That's a business strategy to gain more money through little candies. It's not a good practice and can be reported on since you are forced to buy a certain merchandise against your own will.

It's a common business strategy. At least they give you candy. I used to enter a shop that refuse to return my 50 cents. They said they don't have enough coins so they force me to buy something within the same value. That was dumb! They was lucky because it was me. A friend went into the same shop a couple of days after that. I already know about the coins thing but not my friend. So she was give the same reason. They only need to return her 30 cents. My friend became annoyed and asked for her money back, in a very loud voice. While walking out, she still nagging and mumbling about, still in a very loud voice. I don't think they learn their lesson though... I haven't enter the shop for a very long time, I don't know whether they still practice that strategy.
