On Thursday June 11th at 9:15am I got on a Riverdale bound Bx6 Bus (7683-I could be mistaken) in Bronx, NY after waiting 40+ minutes for the bus. During the 40+ minute wait, a bus drove by with the caption "NEXT BUS PLEASE" on the marquee of the bus. When I got on the next bus at 9:15am, the driver was extremely rude. I know that MTA workers work hard and that their responsibilities can be trying at times, however, customer service is necessary when operating the bus. That's just my opinion. Anyway, when the bus was approaching Southern Boulevard (4 stops after I got on the bus) that driver notified patrons that Southern Boulevard would be the last stop on that bus. At this point, I'm am already 20 minutes late for work and I was not near my destination. I voiced to the driver that he should have announced that as people were getting on the already crowed bus instead of allowing them to get on the bus then get off the bus shortly after getting on. He told me there were implications on the side of the bus stating that Southern Boulevard would be the last stop. I replied stating "no one is paying much attention to the side of the bus when they have been waiting 40+ minutes for a bus. Our focus is to actually getting on the bus". He replied by telling me that I need to read. At this point I lost it because he was being rude and disrespectful. I understand that things happen that may cause bus service delays however dealing with a rude bus driver on top of that should never be tolerated. The MTA needs to train their employees with better customer service skills and attitude. Not to mention that the fares for MTA keep increasing while the quality of the service continues to decrease.
