Not the most exciting of topics but please settle an argument for me. This is between DP and I, but I won't say who's who at this point!
'A' received a £20 voucher for a recent birthday, for a shop they wouldn't normally buy from. However they could always buy 'something' from said shop but it would be probably be for the sake of spending the voucher rather than something they actually want.
'B' wants to buy a voucher for a gift for someone else. Budget is £15 and recipient would be right sort of demographic for said shop. B offers A £15 for the voucher so they get to spend the cash on whatever they want.
A thinks B is a cheeky git. B thinks they are doing A a favour. Who IBU?
