Guernsey vs SA - Petrol pumps

I have been here for three months now and I am still amazed at how different things are over here. I just had to post this. I was waiting in the car in what appeared to me to be a closed-down petrol garage for my never-stop-talking future mother-in-law. I then realized that something didn't seem right, I knew for a fact that this garage was open because it is part of the shop where Mathew works. I took a closer look at one of the pumps and burst out laughing when I read the notice on it... PLEASE NOTE THAT THIS IS A SELF HELP SERVICE ...so F-M-I-L explained to me that you had to go inside to pay afterwards. I stared at her in disbelief and asked her whether people don't sometimes drive off without paying. She replied in a very matter-of-fact tone that it does happen, but that it is covered by the insurance. I just can't imagine ANYONE even TRYING to open a self help petrol garage in SA. It would run bankrupt within a month! I just love this place :o)
