Dock workers touching your trailer air lines

So this has happened to me a couple of times and I’m curious if it has happened to you.

On a few occasions, I have docked into a dock and set my tractor breaks but not my trailer breaks. I do this daily out of habit but sometimes the dock workers go to my trailer to unplug my trailer airlines.

At first they are scared and confused because a bunch of air just gets released and it’s extremely loud. Then they get pissed because they expected me to have set it.

All I can say is don’t touch my trailer without permission and just ask me to set my trailer breaks.

I don’t understand how some people can be so arrogant. Imagine if I messed with their vehicles breaks. That’s a lawsuit, I’m not sure what is legal and illegal in this case.

Are they allowed to do that?

 

*Just realized that I used the wrong “Brakes”. My bad

 

I set my parking brake but not the trailer air supply, I was taught that way.

 

Will do now, but shouldn’t they ask me to set it rather than messing with my airline?
