I've had my share of "flamer" instructors and this guy is calm compared to them.
Ken,
Then you had bad instructors. People don't learn by having teachers shout and swear at them. Doubly so when the student was a non-native English speaker as in this case and probably came from a culture that emphasized extreme deference to authority.
This particular instructor should never have been tasked with teaching a foreign student, probably not even a US one.
