i know in my experiences of bus drivers seemingly getting away with murder.
i remember having to get the 51 to school on we didnt half have some nobs
one time the driver was driving on his phone so some kids videoed him on their phone (good job they ignored the schools rule of camera phones not being allowed) and that got passed onto the police and bus company but im sure i saw him the other day
then there was another time when our bus turned up late so was absolutely floggin it along the coastroad. my sister was sat upstairs behind the stairs and fell off her seat and smacked her head on the metal rail infront of the stairs. the driver bought her in and told the women in the office that she was messing around but he wasnt going to make anything out of it cos he didnt want to get her into trouble!!!!
my folks made a formal complaint about him and we found out a few other people had complained about the same guy for different things. u still see him drivin round tho.
reckon id be a bus driver if i won the lottery or summat. £35k to sit on my ass and drive all day
the only difference was it was a women bus driver and instead of giving me the finger she put her finger to her lips and made the cry baby gesture 
so as you can imagine i was a little shocked but never reported it maybe i should have?? anyway i hope you get your apology and he gets his rollocking
