1) Carts everywhere in the parking lot. I've really only seen this in the suburban Stop & Shops.
2) The people who park right NEXT to the cart holder and still don't put their carts away.
3) And that woman who shoved her cart to the side, got in her car, and watched her cart slowly roll into the middle of the lane...and then drove away.

As a multi-grocery store shopper, I have noticed that the people who push their carts in TJs or Whole Foods are a whole different lot. Or, as my finance says while watching these shoppers meander through the aisles... "these hippies cannot navigate". My guess is that some of the TJs and WFs just have more narrow aisles.

As for the Self-Check, I tend to (very purposefully) shop at odd hours, so I love them!
