I did this kid a favor by allowing him to reschedule to a busy day, and I'm glad somebody on this forum understands that.
And then you totally disrespected his time by making him stand outside your door.
Lad, he's paying you, not the other way around.
BTW, my errands were related to a REQUIRED visit to the residency office to sort out my karta pobytu
That's your problem and it has nothing to do with your client.
but the late shower was a result of the 25-minute delay I had to endure while the woman running the new fingerprint technology tried to figure out the computer interface
Again, your problem, not your client's.
Why couldn't you just be normal and have a shower after your scheduled lesson?
Do you stink so badly? Maybe you've never heard of an English shower? It also goes by the name of 'Lynx can' or 'Axe' in Poland, I think.
To "teach him a lesson"? To show him exactly how unimportant he was to you? That's all well and good, but then don't expect your student to humbly suck it up and stay for the lesson.
How very arrogant and distasteful. Unbelievably unprofessional, especially since the client went out of his way to fit BLS's schedule.
But you can see the arrogance, even in light of the reasonable posters telling him he's in the wrong, he's far too blinkered to see it let alone admit it.
Teachers like you give the real, hard-working ones a bad name.
