Can someone please explain the reasons why you enter and exit at the front of a Dublin Bus?? When living in London I regularly used public transport where you enter the bus at the front and pay your money, ring the bell at the stop you want and leave by the exit half way down the bus. I get so frustrated and annoyed to see tourists missing their stop as they have been waiting at the exit, and the bus driver not stopping as the person has not stood at the entrance of the bus. To make it even more confusing the pseudo-exit doors have 'EXIT' displayed! When the bus is crowded it is nearly impossible to battle your way to the front, through standing passengers.
Also why do you have to pay exact fair and Bus Drivers not have change?
