We've already covered the fact that Walmart offering motorized carts to people who need them is a great idea. We're less convinced by the wisdom of tethering several of those carts together. What possible purpose could this serve? Are these shoppers so worried they might lose sight of each other at the breakneck speeds the carts move at that they had to take precautions?
Even if they've tied themselves together for safety, we can't imagine that it makes shopping a pleasant experience. What if you want wine, while someone else wants cheese? Do you just have to wait until everyone else is done on an aisle before you can move on? Did this whole convoy just do laps of the store, like a shopping train? They look like they're headed toward customer service. Maybe they don't actually know each other, and they're going to complain about their carts getting stuck together.
