I’ve seen some of this in grocery store parking lots. I do one of two things, I go to the service desk with the plate number and ask that said owner move vehicle because he/she’s illegally parked or I just go right ahead and call the local cops, have them roll by and ticket the person. Sometimes I’m tempted to call a tow truck but I don’t know how long it would take for one of those to roll by.
Then there are the ones who park in the “fire lane” to run in for a coffee or to pick up a newspaper, or waiting for someone to come out of the store, etc etc etc. For those I call the cops with the plate number, these for some reason are low priority for cops. I’ve called the fire department and they say it’s parking violation and a cop issue.
I bet you get a kick out of calling 911 when you see a fender bender too. People like you make me sick. You are so busy keeping your nose in everyone elses business you feel a need to tattle every little infraction to authorities.
I'm a law abiding citizen and I expect everyone else to be as well. What country do you live in?
