Whilst driving after a hard days work, I started to feel drowsy and decided to pull into the nearest service station, Welcome Break Gordano, at around nine o'clock at night on 24 May 2013. I decided to have a shower and a bite to eat. Returning to my car, I took a nap. On waking, I carried on with my journey. A few days later I received a Parking Charge Notice from Parking Eye stating that I had overstayed my entitlement by four hours. The charge due is £100 but only £60 if paid within 14 days. Should I pay a gratia payment of £10 instead of the £100? Seeing the signs on the motorway warning drivers that 'Tiredness Can Kill', what should I do?
