In this age of quick communication, when time spent in running errands or writing unnecessary letters is money wasted, the plumbing contractor should have a telephone in his office and in his home. If he is doing a strictly contracting business and only handling new work, he must of necessity be in communication with his office at all times, and if he does a jobbing business many orders will be lost if people cannot reach him by phone. Indeed, if jobbing is catered to the plumber should have his home telephone number on all his stationery, with a statement that a call at that number would bring a man, day or night, in case of emergency. The money saved by workmen calling up the office for instructions or to order goods, will alone pay for the telephone many times over during the year, not to mention the various other savings and conveniences attendant on the use of the telephone.
