I can't tell you how many times I've ran to catch a certain bus at a certain time and stop, and it's been early, or I've watched it just go by because it's early, so yes I've missed it because it was early.
Then sometimes, I'm on that bus that would be picking me up at the stop that I'm missing because of early bus, and this time the driver waits for the scheduled time, or the bus is late.
What the flying fuck?
