Was on SEA-PEK last year and watched this dude drink him self silly in the Skyclub and then proceed to board the plane in BE a few rows from me. Was totally unable to get his carry on the ovedhead bin and actually fell backward into the aisle on one attempt. Pretty funny. The FA decided to remove him from the plane, and after a few minutes of apologies and protests the police came and escorted him off. However long story short, he was lucky as we lost an engine (767) a few hours out and had to return to SEA and try again the next day.
