Passenger: “Is there something wrong with the air conditioning on this tram?  It’s something like five degrees warmer in here than it is outside.”

I get out and gauge the temperature in the passenger area.

Me: “Yikes, you’re right.  I’ll ‘reboot’ the tram in a couple stops when we’re out of the way of other traffic.  If that doesn’t fix it, I’ll have to try for a replacement tram at the depot.  Thank you for letting me know about this.”

Passenger gives me a look of total confusion/disgust/oppression and walks off shaking his head.  I try to work out how I could possibly have offended him with that response.
