Relative on my dad's side (well, his brother): he'd invite us over to stay (good 3 or 4 hours drive). We'd show up and his house would be empty of food. So he'd insist that we need to go shopping. So off we go to supermarket. He'd fill the trolley full of pricey stuff and expect my mum to pay and prep it all. He did this each and every time. He stayed at our place to house sit when we went away. Mum would ensure fridge was full of food for him, Dad would ensure plenty of wine/beer for him to drink. He got free use of one of my parent's cars (and Dad would ensure it was filled with fuel). We'd get back from holiday. House would be empty of groceries - he'd not even buy a bottle of milk and a loaf of bread to tide us over a night/morning - so off to the shops we go...where he'd fill the trolley up with stuff he wanted, not offer to pay for any of it....and would take the stuff he wanted home with him. God rest his soul, I don't recall him ever putting his wallet out to chip in or pay for anything.
Family friends of my parents: lovely people, invited us for a BBQ. We show up. There's a single burger with a bread roll each, one chipolata each for the adults (kids got half a chipolata each), and half a chicken wing each. Oh, and some lettuce. We were starving!! Mum and Dad had asked if we could bring anything or contribute food, but were told not to as "there was loads of food"....so they bought a couple of bottles of wine and some flowers and chocolates for the friends.
This next one makes me smile and look back fondly really. Another of my Dad's relatives, an elderly aunt of his. Lovely lady - she'd been a nurse in WW2. She lived a few hours away from us and would invite us over to stay. She was a widow and living off a pension, so without fail, we'd show up laden with food (and Dad would insist on helping her out as much as possible so she wouldn't be out of pocket due to us staying there, using more water/electric/gas etc). When she'd prep meals, it would be a slice of bread each, one slice of ham or cheese each, or one hard boiled egg each (you get the picture), couple of slices of cucumber, couple slices of tomato, one small pickled onion. She'd put out only enough for a tiny bit each. And that was that. My brother and I were young teenagers and would be starving. We used to pool our pocket money and disappear off to find the nearest corner shop to buy ourselves more food so we didn't go hungry (she lived in the middle of nowhere, so this wasn't easy). We didn't have the heart to say anything to her, as we loved her and didn't want to upset her. We didn't dare say anything to our parents either, in case they got cross with us. As kids, we also thought that she'd never got out of the mindset of rationing. Funny thing was when we'd take her out for meals, she'd order the biggest 3 course meals on the menu and polish off the lot!!
