I would say no one would be that stupid, but someone did stand in the queue for the 22 at DBS, the other day, then rush over to the X22, complaining that it had arrived in the wrong stand. They got on it and went off in it, so I really hope they didn't get a nasty surprise when they ended up travelling through CLS!
