Why you should bag your oranges?

Tonight, I ran to the swimming pool for a workout and stopped by the grocery stores to buy some food for dinner. I grabbed some pita, meat, and dried cherries and headed over to the self-checkout area and waited for my turn. There was an older couple just ahead of me having some trouble. The norm is for folks to put all their oranges in a bag when selecting them from the boxes. This couple didn't know this so they were trying to place all their oranges on the scale but they kept on rolling off and landing on the floor. The eventually decided on the divide and conquer approach which is place as many oranges as can fit on the scale and then to weigh them before weighing the next batch. The machine didn't like this as they forgot a little detail which is that you have to tell the scale in advance what it is weighing before it will weigh it. They eventually got it sorted out but it was comical as they would have a handful of oranges on the scale and then one would fall off and the machine would start beeping and saying that they should see the attendant. The moral of the story is to put all your oranges in one bag and to place them on the scale together.
