We had a bbq at the weekend and asked PIL to join us, FIL text me the day before to ask if they should bring anything and I said no need unless they wanted something special, the next day they turned up with 3 carrier bags of food including homemade quiche, sausage rolls, 16 burgers, 2 packs of sausages, salad,18 bread buns and two desserts, a multipack of crisps and god knows what else.
For context there were 4 of us and 1 small child. MIL has got form for over catering but AIBU to think it’s a bit rude to turn up with that much food when you’re not the host, it felt like she didn’t trust us to buy enough food to feed them properly.
