I’d let it go.
I got a ticket under similar circumstances. Stupid machine only accepted coins, so I went across the road to the bank to get change.
On the way out, a little old lady tripped over the kerb outside, fell over and landed in the road on her head.
She was in a real state physically, and more than a bit confused, so I stayed with her, tried to keep her warm (it was February) and calld an ambulance.
An hour and a half later, it turned up. The ambo’s took her off and I went back to the car.
Of course I found a ticket.
I naively tried to appeal to the better nature of the company issuing the fine, and lodged a dispute. It was rejected as the ticket had been ‘correctly issued’,
So the moral of that story is don’t stop to help those in need 😄
I’ve put it down to experience, and hope that by some form of karma, I’ll get a reward. Or else the parking enforcers will suffer some terrible fate because no-one stops for them.
