Encouraging Teacher
We know that this teacher thought this was a clever push of encouragement, but it’s anything but. This was a pretty insulting gesture on the part of the teacher. If a student did not perform well on a test, it’s safe to assume that they need a bit of extra attention and focus to find out where they are having the most trouble on the subject.
The teacher should be able to help the student find their way through the problem, not scare them through it. It’s also worth noting that it’s also insulting to assume that people who work in fast food establishments are not or were not good students.
