Ever heard of filling a fuel truck with the wrong fuel?
Its happened before.
The trucks at big airports are also part of the central system, same fuel, same SOP. Airlines ensure their fuel system has better standards then the one at the GA FBO.
Unless you hired an off airport service, which would need an access agreement, and pay taxes and fees.
