This reminds me of an event once in our family.
There was a barbecue arranged for my FIL’s family to meet his new girlfriend, hosted by the girlfriend. He had made a big deal about her wonderful hosting.
We travelled 2 hours to get there, but his family (2 sisters + brother + spouses + one adult son) had travelled 5 hours, and had all paid for accommodation.
She had purchased long sausages, and the food was budgeted at half a sausage in a finger roll per person and a plain finger roll for the vegetarians. No other food provided.
There was no food provided for my 2 year old as the GF “didn’t think the baby needed to eat”. My husband spotted a fruit bowl and asked if she could at least have an apple, to which the answer was “not really”, so she had my half sausage.
It was hugely embarrassing. We would visit the relatives in their area each year and they truly were hospitable.
We ended up taking them all to the pub on the pretext of taking everyone for a nice walk to the beach.
It was a completely bizarre situation. This wasn’t due to money issues. It was purely that she felt that that was an appropriate amount of food to organise - half a long sausage per meat eater, one finger roll per adult, nothing for a toddler, with no extras. I wondered about disordered eating, but we had taken them out for a meal a couple of times before that barbecue and she seemed to have a normal appetite. She also witnessed that my toddler did indeed eat food on those occasions.
