You know what really grinds my gears? People with bad shopping etiquette.
1. People who stop their cart in the middle of an aisle and stand right beside it. What are you thinking? You don’t park your car in the middle of the road. How is this any different? This hardly leaves enough room for one cart to get by, let alone two-way cart traffic. Observe:
2. Don’t stand so close to me. Everyone needs their personal space and if you’re standing one foot away from somebody in line chances are they’re going to be uncomfortable.
Note that 1.5 feet or less is intimate space. Unless you’re trying to get intimate with me, give me my space (and if you are trying to get intimate with me, I’m already taken)
