Our whole ambulance company does this thing where when we go to hospital if we see another rig from our company we turn on the light and sirens when it’s off so when they get in and turn it on they get jumped scared by the lights and siren.It’s happened to us multiple times and we’ve done it to other people multiple times. Today we did it and they reported us to dispatch and the shift manger called us and was pissed. We tried to explain that everyone does it and we didn’t even know it was a big deal but the guy just said you guys were the ones who did it that’s all that matters.They said they are gonna write a written report and get back to us. I think we shouldn’t sign anything saying we’re at fault if they try to give us a write up. And just hope they don’t go straight to firing us.
