Waiting in line at the checkout (small Sainsbury's only two checkouts and only one woman serving)
There was two people in front of me and one behind.
Random woman butts in, has a loaf of bread and put her coins down on the counter and walks off. Woman at the check out shouts that she needs to scan the bread first, which she then does and random woman leaves.
The check out woman then says, Oh she's always doing that.
aibu to think that this woman should have been made to wait like the rest of us?
