Traffic Warden

Hi All
I rarely go into town either early or at the weekends. I remember when I was working, feeling well p****d off with the Wrinklies buying their half pound of butter and two slices of ham on a Saturday at the supermarket or early in the morning when I was on my way to work and buying some milk for the office. I would stand behind them in the queue thinking "Why didn't they go in the week when workers were at work?" They had all week to do their shopping and here they were fumbling in their purses for the right change or forgetting their pin number and saying !I'm a silly old fool aren't I?".while the queue of folk on their way to work stretched ever longer. Well now  I AM THAT WRINKLY. I do try to give the right change though I do forget my pin number occasionally, what I try not to do is be that shopper either at the weekend or early in the morning.
There is a reason for this preamble (bear with me)
Last week I went into town at half past nine on a Saturday. I needed sugar from Farmfoods (39p a kilo!) for some jam making,and to take some money to the bank with some urgency for my granddaughter. I'll just pop in I thought. Outside a short row of shops is free short-term parking, where I often park as it is close to the bank and I was lucky enough to find a spot there. As a traffic Warden was leaning against a shop window I made a mental note of the time so as not to over run the parking time. I always think that Traffic Wardens get a bad press and a hard time from the public, so I gave him a little nod as I sped off. Banking done, sugar bought I returned to my car to find a parking ticket on the windscreen . The Traffic Warden was now leaning on another shop window a few yards away. I looked at him and said "WHAT!?" He pointed to a sign high up on a post and said "There's no parking allowed between 7.00 and 10.00 I'm afraid" I was extremely angry and didn't trust myself to speak to him again. I tore the ticket off the windscreen and threw it with my bag in the car and drove away.
NOW I know that ignorance is no excuse so I have paid my fine. HOWEVER, I really feel that the Traffic Warden could have informed me that there was no parking at that time. He watched me park and get out of my car and walk away, I even nodded to him. A couple of words or a meaningful look up at the sign would have sufficed surely. I can't believe that traffic wardens are there purely to give out tickets and not advice.
What do you think?
