Whilst Not the case with all QF Crew, on many occasions I have got up to walk about and have a chat as a Pax, the large majority give you the evil look of death (the one you get when you press the call button from QF crew) as you approach the galley (the how dare you come up and disturb me look this is my break leave me alone). Needless to say one tends to veer away and keep walking.
Luckily every now and again a chatty crew member proves this wrong and tends to help repair the angst of other crew members (possiby perceived) actions.
