Metro inspectors are fining almost 100 men a day for entering women-only coaches, making it the penalty most commonly incurred by passengers, trumping sneaking into gold class, chewing gum or drinking water. Since March, the Roads and Transport Authority has warned commuters that men will face a Dh100 fine if they intrude into the women and children space on the trains. Large pink signs inside coaches and on platforms clearly mark out the area, although this has not stopped many men from boarding.
