DEAR MISS MANNERS: I have worked retail and customer service jobs for about 20 years. Whenever an item is not scanning, out comes the old joke that if it doesn’t scan, it’s free. I just looked at a customer and informed him that even on my very first day of retail, that joke has never been funny. He then told me I do not have a sense of humor. Why, WHY do people think jokes like that are funny? They really are not. And some people, instead of joking, are even being serious! If the item doesn’t scan, rather than try and get a price for the item, they want the cashier to just give it to them! No…
