I love Sainsburys. Just found a button on the self-checkout machines that says “cancel payment”. If you press it you can walk out of the store without paying.
Knocked on my neighbours door and just had the following conversation.
Me: Your son has just run out in front of my car, I nearly killed him!! Neighbour: I’m so sorry, he won’t be doing it again. Me: I know he won’t, the paramedic said he probably won’t walk again.
