Sitting as a Cashier

While on register this morning, I remembered the time I was in Germany. I went to the grocery store and was in shock when I saw all of the cashiers sitting on stools while scanning groceries! I was very jealous. I wish I could do that. Today my knees were hurting me from standing for so long and not moving. I must be old. Then I got thinking. It'd probably be hard to scan the groceries while sitting down. I would have to lean over to reach the groceries. Then my back would hurt. I also feel like sitting down is the lazy way out. When I was 17, of course seeing cashiers sitting down on the job was awesome. Now that I'm 26, I think I have changed my mind. Maybe sitting down on the job isn't the best thing at all.
