A few months ago, I was on a n/b B49 and we pulled into Ocean Pkwy & Avenue U. Relief Operator was tardy by 30 minutes. Apparently, she was traveling on a B3, dunno if it was late but I think it wasn't even the first B3 to arrive, it was maybe the second or third one. Later on, along the route, we were passed by an empty B49. Smh, I would understand if you were several minutes late but not 30 minutes late. Made the bus ride miserable. The original operator was pissed as well cause he can't leave the bus unattended.
