The great unwashed !
I had to fly down from BKK to KUL last week, on a Thai 777 flight. Nice enough, but holy schmoley, have these people never heard of deoderant ?
I was amazed, nay appalled at the personal hygeine standards of the population collected in the holding pen at the gate. Almost every where I tried to sit / stand or loiter, I was subjected to an almighty pong !
Thinking about it, maybe it was me !
p.s. It wasn't, I had just got out of the shower into clean clothes, and used industrial strength deoderant, confindent in the marketing promise that "it wouldn't let me down!"
