It's been a few years, so I can look back on the time period I needed to use an electric cart at the grocery store. Three favorite situations:
"Hey, Grandma, want to go on a hike?" "No, kids, Grandma needs your help learning to drive an electric cart at the store."
What happens when one nicks the corner of the tall display with tortillas in slippery plastic wrappers.
When the produce clerk says "Hi," and asks "What's wrong with you? You don't look abnormal."
