A couple of years ago on Ted I was in the aisle and the FA was leaning over me pouring lemonade to the person in the window and spilled it on me.
It wasn't the accident that p*ssed me off so much, it was the fact that she didn't apologize. I asked her for a paper towel and she acted like I was imposing on her. I didn't think I was entitled to compensation, but I did think that the FA was entitled to a lesson in customer service.
