One time in I asked my English teacher if I could go to the bathroom and he said the ‘I don’t know, can you’ line like it was something new and clever and my mind just sort of went stupid and I told him that if there was a colloquial gap between ‘can I’ and ‘may I’ that was significant enough to genuinely confuse him in the context of a classroom then maybe he shouldn’t be teaching highschool English, and what nobody tells you about that sort of situation is that no matter how good it feels, you do have to come back and finish the rest of the class
