Lmfao, this happened to my bus all the time. We would all just get called down to the office and the person would stand up. Video cameras were never used. If you explain the situation im sure you will not get in any trouble.
one of the bus driver's my school uses is some guy who pulls over the bus if he see's you eating or if you are not facing the front or if you are not sitting down correctly and when the class get's off he will take a look through the bus =.=
but i doubt anything will happen teachers/bus drivers will threaten but do nothing i bet its cause they like the rush they get because of their suspected authority over people younger than them?
