Actual bus service is fine for getting from point A to point B. Is very inconsistent in terms of customer service; have met a few drivers that were pleasant, but not recently. As somebody who avails of the aircoach relatively infrequently, I was not aware that the young adult fare is for online purchases only. This is completely fine, however the tone and volume of voice which the driver used communicate this fact today was not. I found the delivery unnecessarily impolite and condescending. On the journey preceding todays, a different driver was very rude in telling me that a leap card cannot be used for journeys outbound from T1. I then had to disembark the bus into a downpour of rain and pay for a ticket with cash at the booth. I am an infrequent user and was not aware of this system of purchasing tickets. I have no issue with this, but again this interaction with the driver was uncomfortable, off-putting and embarrassing. These unpleasant interactions, aside from awkward rules around purchasing tickets, will be my primary deterrent from using these services in the future.
