I was at the supermarket earlier and an elderly woman was having a bit of chat with the checkout operator. Nothing major, she wasn't just standing there for ten minutes gabbing away. But she was talking as she packed her bags and a couple of times leant over to hear better what the checkout operator was saying to her.
A youngish woman in front of me with a little boy in tow was muttering and glaring and even turned around to me on one occasion and rolled her eyes.
AIBU in thinking there's a happy medium between causing unreasonable delays at the checkout, and expecting everyone to rush through at top speed without exchanging the slightest bit of conversation with the staff?
