Wolfie, when I queried as to why I hadn't been given the discount last time, I was told it was due to my not giving them the info on my TIE card. At the time, I hadn't got one, just the stupid paper one. All my details were on the paper plus my Spanish driving licence but that was not sufficient. After I gave them the Card to look at and record, I was told I was eligible for the govt discount. I asked why they needed it as I never needed to produce it each time I filled the car up - I was given the usual shrug of the shoulders... Apparently you need to be registered with a company now in order to get the cheaper diesel than at the local garages.
