How to confuse the customer

In Vancouver all gasoline purchases must be paid in advance. You can either pay at the pump, or pay the cashier. If you pay at the pump you must follow the instructions on the pump.

The problem I have with this system is that the instructions on the pump are contradictory. The diagram printed on the pump shows that you should insert the card with the magnetic stripe to the left.

The diagram shows on the pump's display window shows that you should insert the card with the magnetic stripe to the right.

So, which is the correct way to insert your credit card? And why has no one noticed this before? Perhaps it just goes to show that no one, customers or staff, really pays any attention to these instructions. Never a good sign.
