Jesus, you just reminded me how much I hated taking the bus to high school back in 2011-2012. The Manhattan bound Bx03 and Bx36 are so bad for this exact reason! Buses takes forever to come, and by the time it does its crammed with people in the front. Can't even get on. Then when the thing drives by there's all this space in the back. So infuriating, it was usually better for me to walk across the Washington Bridge than wait for another one.
