I used to play MTG, if some Japanese guy who didn’t speak a lick of English and had all JP cards showed up at Commander night I’d be pissed, and that was casual, at a tournament it'd be even worse, so no, the shop didn't do anything wrong.
Lol if that happened over here the night would grind to a halt on their behalf and anyone who so much as made a frustrated noise would be thrown out and/or banned.

I would totally play with them. Arguing over rules by grunting like cavemen because that is the only language we have in common would be hilarious
