On the 2pm bus from Cork to Dublin City Centre on Thursday 2nd Nov. Aircoach cut corners by using the same bus as the incoming Dublin to Cork service and just swapping the driver. The incoming bus arrived at 2.20pm and passengers disembarked. Bus departed 35 mins late from Cork. As a result I was told we were going straight to Dublin Airport and to get the 700 back into the city centre. I'm now over four hours into what should be a 3 hour journey and not there yet. Plus the driver of the 700 is the angriest man I've ever met. Shouted at customers at T1 and T2. Reminds me of the film "Inside out" where the bus driver only has one emotion - anger. Not impressed Aircoach.
