Please help settle a debate. I was reminiscing with a friend about the 50p mix up I used to get a kid at the local corner shop. She laughed at me and said it’s not called a mix up is called a pick n mix. I correctly told her that a pick n mix is the overly expensive sweets you pay for per 100g and comes in the snazzy stripy bags at the cinema whereas a mix up is a small selection of penny sweets that come In a small white bag. She completely disagrees and now I’m unsure if I’m wrong.
YANBU it’s definitely called a mix up and your friend is a Wally.
YABU it’s a pick n mix and you have been saying it wrong your whole life.
