I got few items from reliance smart today and when I went for the billing of the items, the cashier told me that since the amount is more than 1000, I will get medium-sized apples for Rs 4. So I told her to add it to the bill
Now, when I came back home and checked the bill, the amount for the apples were added to the bill. i know the amount is small but why would the cashier say something like this
