Q: It drives me crazy when someone’s cart blocks the aisle in the grocery store. Should I move it or should I say something to the person?
A: Short of shopping at 3:00 a.m., you’re unlikely to make it through the store without a cart jam. A polite “excuse me” usually works, but you may have to repeat yourself, especially if the person is on a quest to find the cereal with the highest fiber content. If there’s no one in sight, push the cart aside gently.
