I was opining that what is "tolerated" is not necessarily "legal" in the strictest sense,
Was that paid-trial-lesson-by-a-PPL-without-AOC ever "tolerated" then by the authorities? Or did they simply not know what was going on, and stamped it out as soon as they learned what was happening?
In our case it's not so much "tolerated" but "encouraged" or even "applauded" by the government.
