Let's say a couple have a small argument about helping out a friend of one of them.
The couple live in different places for work reasons. They regularly go back and forth to see each other. One of them has a friend who asks them to take an amount of cash (approx €1,500) and exchange it in the other location to get a better rate, and because it's easier to do it due to language issues.
The other partner is not happy to do this because, mainly they don't want to be responsible for the money, as well as having to exchange it and think about it. They would be happy to escort the person around if that person visited, but not to actually take charge of the money.
Would you do this as a favour? Is it strange not to? Is it weird to be annoyed at someone who doesn't want to do it.
