Before we left Cork on the 13th September at 11pm, the driver said that the toilet was not working due to technical difficulties. It is a 3.5hr trip and toilet facilities should be available. On my he way to Dublin, before Portlaoise, the driver pulled the bus into the hard shoulder, stopped, stated that he needed to stretch his legs and went outside clearly to have a cigarette as he could be seen doing so and there was a very strong cigarette smell when he re-entered the bus. This is dangerous and unsafe and should not occur. I felt unsafe and would try not to use the Aircoach service again sue to this.
