But why do you return to reception to report those?
If they're known faults they're documented in the aircraft log book, which you checked before signing for the aircraft, so you knew perfectly well those bits weren't working.
Having said which I did once discover a previously unknown non-functioning beacon:
"Er, the beacon doesn't work."
"Oh. Hmm. We're a bit short of an alternative aircraft to give you just right now. Do the strobes work?"
"Yes."
"So, if you went flying you'd feel that you were just as safe with the strobes on, even if not exactly technically legal?"
"Yes."
"So, how's about you discover the failed beacon at the end of your flight, then, rather than at the beginning? Given that the alternative is to scratch your booking?"
I said yes, of course. A certain amount of common sense does have to be applied sometimes! Like, I also wouldn't be bothered about nav lights and pitot in good visibility day VFR.
