I hear from the new GMIS that the PEY punters are now asking for pre-departure drinks. If they want to be treated like they are in J class, then they should buy a J class ticket. I would say that the 10 cabin crew we have on board the PEY Busses are a tad too busy for drinkey-poos.
This might be because the airline advertises welcome drinks as part of the service:
You will be greeted with a welcome drink of champagne and juice and a hot towel
