Was I too rude to my dance instructor after his fake smile?

Went to a dance class for the first time

it was like a course but they also accept drop ins

I told the instructor I was a drop in (to shoe proof of payment).

he said: Yeah I think I saw that.

You can get set up there or whatever

*Fake perfunctory smile
