I don’t believe in nor partake of such “priviledges”, but it’s the owner’s prerogative to offer them.
If I did take advantage of such a priviledge, I’d have simply kept the “note”...and parked there the next time I visited that establishment.
Then I’d wait for the ahole to mess with my vehicle and confront them...
On that point I agree. I served Cold War. I would leave the spot open for wounded combat vets. I could use the walk anyway.
