On my latest set of AA domestic flights, I had complimentary drinks services. On all my flights I asked for Cranberry Juice.... in all cases, the FA wanted to serve me only a glass. My memory tells me they used to leave you the can.... Ive had to ask to get the entire can with me, and in one case I got an almost empty can because my drink was poured from an open can. Is there some management directive to save on drinks.... Are you expected to offer to pay for a soda to get a full can...? Please discuss.
