This is in response to the letter "Check cellphones at theater door?" [July 14].

I'm against this because cellphones are a necessity in an emergency.

When attending movies, meetings, church services, bingo, etc., people are asked to silence their cellphones or put them on vibrate. This is usually an adequate request and allows people to still have access to their phones.

If they fail to silence the phones, usually there is another request. If the phone rings again, people in the audience will yell out, "Shut off your cellphone!" That usually gets results.

Why not eject violators from the audience?
