turn off your mobile phone in the priority seat

some says its because of the pace makers that old people wear, but
based on this poster, it seems that it’s simply because of potential
annoyance.
so this does not communicate clearly whether it’s to cut off the sheer
electromagnetic field that can actually cause invisible damage or to
encourage the social discretion (i.e., no need to turn off the phone
but shouldnt use it)
