If you ever get to see petrol forecourts over a long period of time, some of things people do really do make you wonder. One of my personal favourites was the guy topping up his oil, by pouring it down the dipstick tube
Had the same thing in the 80's with a lass in a little Fiat on my forecourt. Or the woman who pulled into the garage while her car was on fire. Or the woman who'd driven 4 miles on a flat tyre but 'only thought the wheel was loose'. Or the 2 women who asked if they were on the right road to Scarborough ( i'm in Durham, they'd driven from Harrogate. Check the map)
The list is endless.
