Was on a 145 outbound this morning - probably the 0730, as I boarded it around 0815 at Cornelscourt (AV137).
Three Revenue Protection officers boarded at Cabinteely, and caught the passengers in a classic pincer movement - one upstairs, one down, and one at the door to catch the stampede of people who suddenly remembered that they had to get off in a hurry.
Don't know about upstairs, but several of all ages and genders were caught over-riding by the two downstairs.
This should happen more often.
