Inbound and outbound journey to Kildare St both took far longer than timetabled due to traffic. Don't timetable journeys as 45 mins if the rush-hour traffic - which is always there - is going to make them take almost twice as long. Driver on the inbound service was fine - but the driver on the service back to the airport (20/9/23, 18:07 from St Stephens Green) was miserable as hell. Didn't speak one word to me - no greeting, no 'that'll be 8 euro please', no 'thank you', no 'goodbye' in response to mine, not one single word. Just stared at me and pointed at the ticket machine when he wanted me to pay. I guess some people just aren't cut out for customer-facing roles, and he definitely isn't.
