A friend hears about a great buffet. He goes. He loves Caesar Salad, so he loads up. It's amazing, so he recommends the buffet to you and his friends.
Everybody else chooses the food that's already their favourite, so everyone has a different experience based on their predilections. His steak loving friends hate it - the meat is tough and dry. You love seafood, and end up spending the night on the toilet. You send your friend angry text messages.
Generalities mask the truth. Getting specific about context reveals it.
Be wary of buffet recommendations and generalities. Your stomach will thank you.
