Did you put a hefty dent in a blue Toyota Auris in Waitrose car park?

Dear Formby Bubble:Yesterday afternoon whilst parked in the Waitrose carpark for shopping there and elsewhere my blue Toyota Auris Hybrid estate received a hefty dent on the driver's door. No note was left for me to contact the owners, who must have known they had done several hundred pounds worth of damage. 

I wonder if the owner reading this would contact you with their details - or if anyone saw the incident? Thank you!
