Ok, let's remember that the OP was talking about an Instructor turning the fuel off. I am still struggling to understand why that would teach me anything (other than the instructor has poor judgement).
Regarding flying in bad weather/strong winds and experiencing spins etc, I can tell you that nearly all the GA pilots I know go for 60 mins max when the weather is reasonably ok (I work at an aero club). And why shouldn't they? Unless you are very well off, it is reasonable to wait for good weather so you (and your passengers) can enjoy the flight.
Nothing wrong with that.
