The only thing that worries me about flying business class is the fact that I may run into a couple of rowdy Scots who keep me in the bar for the entire trip, denying me the use of the comfy chair I had paid for.
Would be like the night I splashed out on a five-star room in BKK one night only to get caught up with some irresponsible fellow Aussies who kept me out drinking all night. Got back to the room in time to shower and checkout. Did not even get to pull the sheets back.

(my level of taste usually peaks at "Dynasty" level and to be honest I sleep just as well there as I do at the Siam City)
