I had one that kept nodding of on the expressway. I was in the back-seat paying no attention when another taxi pulled alongside and franticly got my attention about what was going on. We were probably doing 100kmh I gave him a shake to wake him up without startling the kunt, he was good for about another 5 kms then fell asleep again. I yelled at him to pull over so I could get the fuck out. But he continued and I yelled at him all the way to sukhumvit. Fucking guy must of been coming of a ya ba bender.
