Carrying a weapon on the metro? AED 200 fine. Falling asleep on the metro? That'll be AED 300 please. That's right, it costs more to fall asleep on the metro than it does to carry 'weapons, flammable articles or any hazardous material.'

 A US based student found that out the hard way. She fell asleep on the metro and was woken up by the ticketing inspector and slapped with a AED 300 fine.

Two train attendants confirmed that passengers caught taking a nap inside the train may be fined. But one of them gave a qualified answer: "If a passenger falls sleep and snores or disturbs others - by drooling or falling over on to someone else's space - that can invite a fine.
