I think it may not be a bad idea that passengers have to pay for everything. My worst example refers to champagne, a drink I do not appreciate. When offerered a drink before departure with CX (sparkling wine, sparkling water or juice) I always asked for a glass of red wine, and I got it. I think the same may have happened with AY some few times, but recently AY refused. Now it is champagne or water, red wine is for dinner only.

Otherwise, AY is quite good to break down all extras (seat selection, wifi, or whatever). I like. But, please, don't force me to finance other peoples' champagne.
