Yes, this happened to me just recently, I was supposed to be out of my school for dentist (which was for 12:55am), for 11:00am, but they let me out at 11:15am. I was in a big panic moment as I had to rush all the way to the bust stop which was about a fifteen minute walk at a really fast pace, then when I got there to meeting my mum, the bus was right there but I was still halfway down the street I tried running to the bus my mum doing the same but from the right side of the street I was on the left side. When we got there, the bus happened to think it was a good time to go, I just wanted to scream very loudly in the street: "NOOOOOOOOO, GOD DAMN YOU BUS, GET BACK HERE!".
I did get to dentist on time though, five minutes early in fact.
