I had the same EXACT thing happen last year! I wasn't in any hurry, and was enjoying my time alone. I encountered this woman and her daughter in one aisle, and waited patiently while they completely blocked the aisle. I wasn't giving them dirty looks or anything, I was off in my own little world. Eventually they moved on, and I got what I needed. I turned the corner, and there they were again. I stopped, and was daydreaming about what kind of cereal I should get, when the lady suddenly started yelling at me for being rude! I was :confused:. I smiled and said I wasn't in any hurry, and that really set her off! I mumbled something about rude people who block the aisle and don't pay attention to their surroundings, but I got out of there pronto because she looked like she was going to punch me.
It still bothers me. :glare:
