Sat in WT+ this morning on BA165 and along comes a lady who sits in the row behind me, immediately summons the crew and says 'my husband tried to upgrade but was told there were no seats - the row is empty, can he sit here?' Crew said they'd ask the 'manager' and get back to her.

Halfway through the flight, husband appears and plonks himself next to his wife. When I saw the CSM walking through the cabin later, I mentioned that there was someone sat in the seat behind me who wasn't there when we took off. She said something about it being too much hassle to deal with, at which point I said I'd love to sit in Club or First if there were free seats but recognise that I obviously had to sit where I paid. She agreed with me on the principle (asking me if I'd like to sit in the cockpit!), but did absolutely nothing to send the man back to his paid for seat. Then spoke to the man, who tells her that 'a member of crew said I could sit here' and decided to leave him alone - isn't the CSM meant to be the person in charge on board in these situations?
