Seriously though I'd call the real police in 2 seconds. There's no circumstance this is a legal procedure. To have a boot put on during the minutes that the worlds largest delivery company (aside from Amazon technically) is making a delivery. In what looks like a reasonable parked position even if not technically a parking spot but delivery trucks always have to use spaces not meant for long term parking. Guys in cities have to double park all day, no choice. While waiting for police, get off those stops and enjoy a break.
