I have two purposes for these rubber bands and they are perfect. I use them to attach an info folder to my jelly and as an internal structure to my bottle socks.
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.
