we're all speedy boarding plus card holders
You may be, but the rest of the family are not, unless they have purchased cards at the massive discount that staff family members are offered....and friends certainly are not....and they board late with hangovers.
Most crews are brilliant, but you still have a few who need weeding out.
It has happened to me twice with a MAN based crew and once at LPL. PM me and I can describe the guilty parties. They may already have left the company, as I have not seen them on flights this year.
