Supermarkets are keenly installing machines that turn your loose change into shopping vouchers.
These machines are proving to be very popular with lazy customers, who cannot be bothered to bank their change, and with the supermarkets who make a nice profit on them.
They charge around 7% on the money tendered, and then only offer the customer a voucher; which they have to use "in store".
Now even the most dim witted individual should be able to see that it would be far better for the customer, if he/she has already bothered to take their loose change to the supermarket, to spend that cash directly and not lose the 7%.
Seemingly, some people deserve to be ripped off!
