Got a new phone? Leave your discarded one in the bin in the community center lobby. Our police department has a cellular phone program.
Don't talk on your cell phone in the library, turn off the ringer. You aren't supposed to disturb others in libraries. Would you leave the ringer on in a movie? We do provide places where you can talk on your phone without annoying people: room A and the little lobby areas between the inner and outer doors. Text messaging? As long as the ringer is off this is usually not rude in a library.
If you are using an AED (Automated External Defibrillator), throw both your cell phone and the victim's out of range. 911 has already been called, right?
And if you are on a date and your cell phone rings - turn it off without looking.
