Now that cash registers do all the math, no one has to count change back to a customer anymore. Unfortunately, this has introduced an irritating, omnipresent annoyance. When you get change back today, it’s bills first, then coins on top. What happens? Half the coins try to slide off the bills before you can grab them – a problem that could be easily eliminated by going old school, placing coins in the customer’s palm first, followed by the bills. As annoying as the new way is, it points to a larger question. Is there some little thing about the way you or your people serve customers that’s a small but continual annoyance? You might want to ask around.
