We spent 5 years cooking a big roast dinner every Sunday for DB, SIL and parents. We were really struggling financially at the time but enjoy cooking and felt it was important to spend time with family.
DB & SIL are fairly well off. They have started a new business venture selling food. It's doing very well.
I get a 20% discount from SIL. So instead of paying £5 for lunch I pay £4. They often have some food left at the end of the day.
Is this a bit stingy considering I spent years cooking for them and paying for all the food?
