As a former Hy-Vee employee who worked at customer service and dealt with can/bottle returns the stuff we saw was gross. Nothing like having to reach into bags with broken glass, bugs, pee and pooh, garbage, vomit, you name it, I probably touched it when we took cans back in the store. And trying to tell people their cans had be be clean, you would swear the whole world just collapsed on them. We had people throw cans and bottles at us if asked them to take them out of the bag they were in to get an actual count. We were expected to just believe them when they said they had 100 cans in a plastic grocery bag. My favorite thing to ask them was how would they feel if after taking their cans I was up front sacking groceries touching everything and them wondering if I had washed my hands.
The deposit bill is outdated and needs to be eliminated. Spend the money and develop strong curbside recycling programs. All my cans/bottles go directly in the recycling bin. It is so much easier and I don't have to worry them.
