I flew with a guy like that 2 weeks ago. Snowed for 10 minutes and we ended up with an inch of slush on the wing. He was ****ed when I went outside to double check the wing. He was yelling at me when I said we needed to deice. I told him I didn't want to end up on you tube. He pointed to the rj next to us as it didn't have any snow on it. I said go look at our cold soaked plane, I'll wait. we deiced.......
