Very, very sad - RIP hun.
And yes I concur poor guy may have had a few too many drinks. We've all been there and/or seen it with our own eyes. We Cabin Crew like to drink until we can't walk most of the time and on those walkways ... you can see how it could happen. I fell asleep in a lagoon in Fiji after a few too many drinks and probably wouldn't have woken up if it wasn't for my crew member ... fortunately taught me a lesson and one drink, if any, is enough now.
