As a mogas user, I never carried an empty jerrican. There were no airfields/strips with filling stations near enough for me to be willing to carry 2 full cans back. And carrying a trolley, securely tied down with the cans was too much bother.
Using a taxi would push the cost far above Avgas.
And, while JetA1 is cheaper than diesel, Avgas is dearer than mogas.
