I miss the days of a liquor service after a main meal when the coffee was served and even in WT they'd offer more than just brandy or port - proper liquors.
I really miss the free drink and snack / meal on short haul. Given BOB has not been well received and the slow service / lack of availability drives me nuts, I do miss even on a short flight having a drink and snack/ meal and sitting back. I have compensated for this with a beer out of the lounge, crisps and a plastic container to hold a couple of sandwiches.
On the Toronto to London route, I miss the Long Haul crew. Cranky at times but always excellent service in the biz / first cabins. MF are pleasant and try - but it is just NOT the same.
