Potluck etiquette

A friend of mine asked me my opinion on this and she said it was pretty split -and now I’m curious.

Say you go to a potluck and you bring some food and a bottle of wine and for some reason the hosts don’t put out your food (assume it’s just a mistake- there was so much food and you brought something simple like pita and hummus and it got kind of forgotten). Would you take your contribution home with you when you leave seeing as it wasn’t used? What about the wine?

I personally wouldn’t- they threw a party and it’s my contribution they can enjoy on their own time. However had I brought a dish I put more effort into making, I would probably just ask them if they would eat it or if they’d prefer I take it home with me as I wouldn’t want it to go to waste.

Apparently my friend’s friend couldn’t believe she was leaving behind the wine and food seeing as it went untouched.
