They should be all like that!
Unfortunately there are some CSD's that only sit in their office, eating and watching films throughout the flight and give you the evil eye when you happen to come into "their area" to get some paper work or something out of the duty free trollies. When you think of how much some of they earn...
Sadly that's not an attitude confined to CSD's, it's company-wide, endemic and simply "the BA Way"
