What an interesting (and in some respects revolting!) thread.
Where does one draw the line at malodorous/obnoxious pax?
I got an upgrade to J once (on a trip to Honkers so the upgrade was most welcome!) because the guy sitting next to me not only stank to high heaven, but as soon as he got on he removed his shoes and socks -- his feet had an even worse stench -- and started clipping his toenails!
I had a word with a sympathetic CC and he said, 'There's loads of room in Club, go and sit there for a while and I'll sort you out another seat.'
He never came back. Much appreciated mate.
Do CC have the power/authority to tell people to stop clipping their toenails?
