Not the latest scam!!!
This has gone on for years in FR, in my days on the Flight Deck there the Cabin Crew were forever asking us for our change. Its a pitiful situation for the Cabin Staff and went on every day ( I worked there for 6 years ). But thats only the start of the ROT.
If the cabin takings are short at the end of the days work, then the shortfall is removed from the crews monthly income.
This Airline is a shambles for those who have to work there and while pretending to offer low fares, will rob you blind at every chance. You will get the odd cheap seat, but God help your pocket when they catch you in need or a bit offside.
