FWIW - I don't like my beers with fruit either but I don't realy care if other people do. When we have people over I'll usually cut up a bunch of lemon, limes and oranges for drinks. About half of them get thrown in my homebrew. My dad thinks that IPA's are only drinkable with lemon (vomit rising quickly...)
The thing that I hate is when someone brings over a **cking 6'er of Shanty/sunshine/swill, sticks oranges in the **cking bottles. I find them mixed in with my stash of clean bottles, months later, in the basement and I end up chasing fruit fly's around for the next 2 months.
From now on, if people bring over bottles and cans they take them when they leave.
