I just found the photo below on my laptop. I took it ages ago, but since nothing has changed I thought I show it to you. It is Mark's nearest parking meter and he has thrown money into it for sure. Yes, Mark's house does have off street parking, but for various reasons he sometimes, not very often but once in a while, parks his car on the street.
Parking a car on Mark's road costs slightly less than £2/hr and you have to move your car after 4 hours. But there are times when you can park there for FREE ;-))
