Walked over to the fuel dock to buy a gallon of diesel.
Made my request, "no, can't do! You need to bring your passport and boat papers first. Then I can sell you fuel at the higher international rate" of $4:80TT per litre vs $2.70TT local rate. If you are wondering, yes I did ask to buy at the local rate.... No!
Back to the boat, pick up the papers, back to the fuel dock, more paper work and I get my Diesel from the "International Pump" and I am back to finishing off the filter replacement job.
Oh, the pump attendand said she liked my Aussie Passport.
