I took some stuff to the charity shop and parked on the double yellow line outside In design. I forgot to set the time clock on my blue badge, I did place it in my windscreen. After I had been to the charity shop, I popped round the corner to get a sandwich, I came back and saw the CEO putting the ticket on my car, he said you’ve forgot to set your clock, it says you’ve got three hours so tuff this was at 12.36. Three minutes after he observed my car (he didn’t apply an observation time just straight ticketed it).
Whilst I appreciate that it was my mistake and I should of set my clock, i feel it’s rather harsh just to ticket it without an observation period. Is it worth me appealing this or should I just put this down to my mistake, to slightly complicate things I’m going to be away from Friday.
