Expert controller giving incorrect instructions

As I was ready for take off at runway 1left at Ksfo controller Julius instructs me to line up and wait, which I did. Next he instructs me “ when able turn left and contact ground” so I waited till he figured out he made a mistake but instead after a few seconds he says to me Please follow instructions… which forced me to quit my flight and this is very sad because I won’t have the time to start my flight again

The controller knows what he or she is doing they have to go through loads of test I am doing now there was probably a plane on final and you needed to get out to avoid colliding with the plane listen to the atc

@Julius97 can elaborate on why this occurred. Just drop him a PM :)
