Having been here and done it when i worked for the council
you will get a ticket, you are causing a obstruction and that will be a danger to the public, a member of the police ( PCSO would be the guess ) will give you a ticket
the boss of the company is going to say " oh its allright mate, just park away "
your solution would be to get a backpack, stop and drop of barrel with water in, park van and walk with your pole and backpack, job done
