#25: An Air Mattress Will Do
How would you react if you were asked to buy a double mattress for a five-day stay so that your guest didn’t have to pay for accommodation? Honestly, I’d rather pay for them to stay in a hotel. It’d probably come out cheaper, even for five stars.

This woman knows that the expense is inconsequential as long as somebody else is paying. She also doesn’t mind requesting to borrow someone else’s bed (never mind where they sleep). By the sound of it, I’m not sure I’d want to be spending any time with this mother.
