Collect calls

　It is generally very easy to find a public telephone in the developed countries. Public phones are located in bus and railroad stations, airports, stores, hotels, restaurants, gasoline stations（加油站）, on numerous（许多的） street corners and in most office buildings. From a corner pay-call（街角的付费电话亭）, you pick up the phone, listen for a dial tone（拨号声音）, deposits（放入） a coin or coins (depending on the cost in the area) and then dial the number.

　A person-to-person call（叫人电话） can only be accepted by the particular person you are calling. Thus, if that person is not there, you will not be charged. However, person-to-person and collect calls（对方付费电话） are more expensive than calls dialed directly（自拨电话） because they involve the additional labor cost of an operator. The person being called pays for a " collect" call rather than by the person making the call. If you make a long distance call and get a wrong number, call the operator and explain what happened. This means that you can make the call again to the right number without having to pay more money.
