indeed - back in DF days the crews made a bomb selling this - I recall Madeira flights where the perfums and gifts would be almost empty for the return - well heeled punters - where as on the Palma's etc is was booze n fags
the crews relied on massive DF sales to top up their wages
but that was in the days before BonB catering which today often sees a 4 hour flight to the Canaries or Rhodes where the crew are still struggling to get to the back rows to serve bacon baguettes slimey cheese toasties and teas n coffees and often some pax do not get served - even in 4 hours>
BA crews are now facing the same nonsense on the BA's euro routes with BonB catering
when DF was king the cabin crews had a well oiled routine of a drinks round, the meal service followed by tea n coffee then DF sales and it worked - even on a quick ski flight
cannot see the crew being able to sell DF like they used to if BonB grub causing so much work and passengers not getting served.
