Well if they offered and I already said that I would pay. But they wanted to then no as I offered before they chose to pay so they can’t just change their mind. But there are some circumstances where I would (e.g. skint on money….)
yes i would, because its the right thing to do, if they didn't ask for you to pay them back then don't but in this case they did, so i would pay them back so yes pay them back as soon as possible or they'll be mad at you and not be ur friend or whatever it is they are to you.
