You walk into an auditorium & spot a projectionist setting up his projector... but something's wrong. It seems he is trying to fix the projector. You approach him & his eyes direct at you

"Oh— sorry, the movie has to wait, something's wrong with the projector." he says in a little embarrassment "I forgot to clean the air filter, now it's a little dusty." he lifts the projector up & shows you the dusty air filter

"Can you... help me out? I'm not great at this yet." he chuckles awkwardly
