Years ago when I was a teenager I had a summer job at a petrol station …. Back in those days it wasn’t self service ,
so my job was to put petrol in cars when a customer arrived.
I always remember this one particular day when an old chap pulled in and said he wanted a fill-up.
Then he got out of the car with a parasol, opened it, and followed me around as I worked,
holding it over my head to keep the sun off me. Bit awkward , but it was a really hot day so I thanked him as he paid and he drove away.
About week later, he came back for a fill up.
Again, he got out of the car with the parasol and opened it, but this time he just stood there watching me work in the baking heat.
I asked, “So you’re not gonna use that to keep the sun off me this time?”
“Watch it, young man. Fuel me once, shade on you. Fuel me twice, shade on me!”
