I expect you will tell me this isn't wrong but it really sounds wrong to me. Americans use 'fruits' as the plural of fruit, but I'm pretty sure we just use the word 'fruit' as the plural. Or we would say pieces of fruit.
Irritating examples:
- 'funny' pic of a cat sitting in a fruit bowl saying "sorry about your fruits"
- bugging American student at uni asking "hey, can I have a fruit?" when I had a bag of kiwis. "Yes you may have a piece of fruit" I replied.
Any thoughts or other irritating examples?
