"Excuse me @PeacefulBeijing, you’ve removed all the window cranks from Beijing’s taxis. The windows can’t be opened. I’d like to know, have you considered how awkward it would be if a passenger gets into a cab and the driver breaks wind? What should we do? Should we really say, ‘You’ve farted, right? I can’t open the window here. Could I trouble you to open yours?’ See, I’m in this damn situation right now. I’m about to pass out!"
