This is a more WWYD. I will go with the majority vote here.
I run a business park and it consists of 1000 plus parking bays paid for by individuals on a monthly basis. Parking attendant ticketed a car that had no pass on display. Owner contacted me to state. Apologies I didn't show pass but I have a valid one so can you write the ticket off. Fair enough I think. Then it happens again the next day. So another email blaming the attendant for not recognising their car and I should write it off again. The attendant absoloulty did the right thing so no bashing. Just asking. Should I wrote off 1 or 2 or none. The rules clearly state to display your pass at all times. Many thanks.
