Dunno .. but maybe it has something to do with THIS!
A telephone booth (or telephone box in Ireland and the United Kingdom) is a small structure furnished with a payphone and designed for a telephone user's convenience. Such a booth usually has a door to provide privacy and a window to let others know if the booth is in use. The booth may be furnished with a printed directory of local telephone numbers, and a booth in a formal setting such as a hotel may be furnished with paper and pen and even a seat. An outdoor booth may be made of metal and plastic to withstand the elements and heavy use, while an indoor booth may have more elaborate architecture and furnishings. Most outdoor booths feature the name and logo of the telephone service provider to provide immediate recognizability in unfamiliar surroundings and thus achieve a branding effect.
The telephone booth became common in industrialized countries in the 1910s. Starting in the 1970s pay telephones were less and less commonly placed in booths. In many areas where they were once common, telephone booths have now been completely replaced by non-enclosed pay phones. In the United States, this replacement was caused, at least in part, by an attempt to make the pay telephones more accessible to the handicapped. Many locations that provide pay phones mount the phones on kiosks rather than in booths — this relative lack of privacy and comfort discourages lengthy calls in high-demand areas such as airports.
Special equipment installed in some telephone booths allows a caller to use a computer, a portable fax machine, or a telecommunications device for the deaf.
