Generally a great service. However the drivers don't seem to understand how to set the temperature. I'm on the 10:30 bus from Dublin to Cork and its like a sauna in here. Having first doble-checked with some fellow passengers, I went up to the driver and asked if he could adjust the temp. I noticed on his dashboard that it was set to 28 degrees! He made some adjustments and we felt some cold air come through, but only for a while and it is now as hot as ever. I don't want to ask him again. The heater vent under my seat is red hot. Only an hour left to go thank God.
