I taught an adult English conversation class (in Japan) briefly last year and was paid around 30 dollars for two hour sessions twice a month. This was a volunteer thing, separate from my usual job. It seemed great. I volunteered to do it for free and they insisted on paying me, treated me pretty well. Everything was fine for a while, but I eventually quit because (among other things) the rudeness of the student who employed me. Maybe I should make a note that this man is easily 30+ years old than I am so perhaps that's why he felt he could talk down to me but most people I encounter do not act this way at all. Also, his English is quite good so this was not a communication error. Here are some examples:
* Got grumpy when I tried to help lower level students "I
already know that!" he would insist when I introduced something he knew. Because the other students were very low level, it would have been unwise to introduce difficult material all the time just to appease him. I tried to keep things as balanced as possible, however, and to be accommodating.
* Interrupted constantly; was abrupt and got ruder with each lesson out of the blue. If he didn't understand something, I would explain it, but if it was complex, you would have thought it was my fault English grammar decided to be the way it is based on his behavior
* Didn't call me like he usually did before lessons (he would give me a ride, which I appreciated) because he lost my phone number; eventually it got sorted out and he basically insinuated that I had forgotten we had a lesson that day because I wasn't standing on the sidewalk when he arrived.
*If a student asked me an unrelated question, I would try to help as much as possible. One day a student asked about American proverbs. I said, "Oh, yes, that will make for an interesting comparison. I have a book that compares some Japanese and American proverbs that I can bring next time to discuss." Grumpy student goes, "Oh, you don't have it with you?" in a condescending tone. Yes, because I can read the future and know what unrelated questions are going to be asked, sir!
These probably sound very minor, but the coup de grace to me was this:
Other student: I'm afraid I don't understand [insert grammar point here]
Me: Sure, let me help you.
Grumpy student: I HAVE A QUESTION (yes he was very loud and abrasive)
Me: Please wait a moment. I will help you right after I help her.
Grumpy student: *completely ignores me* I want to know [insert long-winded question]
Me: I understand, but I will get to it right after I help [other student]
Grumpy: *completely ignores me* AND I also want to know [another question].
Lather, rinse, repeat.
I gave in and answered him, but I kind of wish I had just ignored him and helped her first, but that may not have been very Ehell approved. After I helped him, he proceeded to glower as I helped her.
I felt so uncomfortable that I would get anxious before every session. Don't regret quitting at all, as I gave a month's notice. I left the class some resources online and in the area to continue their English studies. Received a text asking me to come back a few months later and politely, but firmly, declined.
