The other day while I was going up and down the aisles at my local Kroger supermarket I was confronted with just such a situation, or at least that what I was supposed to think.
As I was pushing my cart up the aisle past the pickles I saw a man with a cart coming the other way. His cart was empty and he was pulling a small wagon behind him. In the wagon was a small child, a toddler.
When the man (in his 30s I’d say) pulled up next to me he asked me if I had a dollar and could he have it? This guy was rolling through the store panhandling.
