My friend's car broke down, she doesn't have a lot of money and I told her she can borrow mine till she gets hers sorted. I am lucky we have two cars in my household, and we both work from home. She's had it for 3 weeks and she's just returned it with an empty tank. I wouldn't have expect a full tank but at least to leave it as she found it. I know money is tight for many of us so I am wondering AIBU?
