The cashier immediately saw my physical need and asked the same man who had found my rollodex cards to find and bring me rubber bands again from the back of the store. This young cashier struck me as potentially of very high value. I have supervised hundreds (perhaps thousands) of people around the world.
I wish there had been a smaller version to purchase. I needed one quarter of what I had to buy. The price was good so from that standpoint not bad but I'll never use all those rubber bands in my lifetime.
