Cellphones above 30,000ft

Another day and another strange pax.
On one flight from Pekanbaru back to Jakarta two weeks back, we heard a cellphone interference on the radio. Nothing major, didn't make our plane fall out of the sky, but it was damn annoying, especially when ATC noticed it.

One of the junior gals came into the flight deck saying that a pax was sitting on their jumpseat at the rear galley and insisted on chatting her and the F/A 2 up. No engineers were on board so no "male crew" to tell the pax off.

As I had to take a leak, I decided to intervene. Taking a leak at the rear toilet next to the galley did the trick. I talked to one of the girls there about cellphone interference. The guy heard it and he quickly disappeared back into his seat and most likely switched his phone off, coz we never heard it again for the rest of the flight.

Back in the crew room in Jakarta, I was chatting with the F/A 2 and F/A 4 while waiting for the car to take us back home. The F/A 2 said she got the guy's name card and wondered what we should do with it. Should we put it up on the crew board and say "Desperate guy seeks F/A for wife" or should we just burn it. We normally put up a few of those cards, but as part of the joke, the F/A receiving the card should also put her name on it as the poster. Since she already had one up there, we decided to just burn the card.
