On holiday with a friend in her home country. She also brought her 2 year old and MIL who is British like me.
Each time we go out it's a bit of a 'race' to see who can offer to pay, like you have to get in quick and get your card out. Not sure if this is some sort of cultural thing but anyway, at first I was a bit slow as hadn't caught on to it but now I've got the hang of things and paid a few times. I intend to buy thank you meal on final night too to say thanks to family.
However in supermarket earlier where each of us bought a few bits like toiletries and snacks etc. I assumed each would pay for our own given these were more personal items rather than coffee or meal in restaurants.
Her MIL put her items on check out conveyor after my items and I put the separator bar between them. Friend saw me do this and made an exasperated face like she was annoyed and expecting me to pay for MIL items too.
Maybe I've not caught on to something else here too but wouldn't expect to pay for her MIL personal items. AIBU? Her MIL has paid for nothing so far and seems exempt from bill paying.
