Last weekend, I had ridden around 60 miles on my Kawasaki twin when I stopped to fill up, after which the engine began misbehaving. The problem was found to be water in the petrol.
Now, if I'd read this post myself rather than writing it, I'd think, "Bloody idiot - hasn't he learned his lesson?".
BUT - I'm talking different filling stations in different counties selling differently-branded fuels. (Well-known names but not supermarket stuff.) Oh, and two different Kawa twins, too.
In the November incident, the filling station was a fairly isolated business in the Cheshire countryside and the "water-in-petrol" diagnosis was made by my local dealer/repair shop. Last weekend, I fueled up at a very busy place on a well-used Shropshire by-pass and the diagnosis was courtesy of the AA.
