I don't give a s##t what I throw into the works. I was based in LGA for a time. Belive me they have some hard nosed controllers. But I've refused clearances, done go-arounds when they forgot to give me a landing clearance. I'm sure, under their breath, I was cursed to he$$. But, who cares! I stayed in my safe bubble, and nobody got hurt. Except my company. It was their fuel after all!
