It all depends on the mood I am in, whether or not I am up to facing First Class. Some days I feel emotionally strong and can deal with anything. Those days I also feel I can go the extra mile to give the service that is expected. And deal with the cold responses, the rude demands and everything else that happens up there. Most days I can fake it pretty well. But there are some days that one more sarcastic comment, or one more person answering my "would you care for a beverage?" while not bothering to look up at me and I swear I'll scream!!! Those are the days I beg another crew member to trade positions with me. We usually help each other out that way since we've all been there. But those days are few and far between and I am always grateful that on every flight, even in FC there is always at least one passenger that will treat me as though he/she acknowledges that I am a human being with feelings and not just a part of the airplane!
