Cell Phones
When making or receiving a call in a public place, with the exception of some public transportation, it is polite to move away from people who can hear the conversation. It is seen as very inconsiderate to carry on telephone conversations in a loud voice in public, in particular restaurants, offices, museums, and shops. In places like theatres, concerts, or cinemas it is customary to turn off one's cell phone altogether: patrons who do not abide by this rule may be asked to leave, and management will not refund your ticket..
