The most reliable handset

Boss: Hey, take a look at this.......
Me: Uhuh, its a handset.
Boss: Notice anything different?
Me: WTF. Why would they do that? Its crazy!
Boss: Its a Nitsuko or Meisei (I can't recall)

The end of the telephone cable's jack is inserted into the
socket INSIDE the handset. In normal design, the socket
are outside. In this case, the jack's plastic clip is broken
and to change it, you'd have to open the handset to do the
change. One customer got pissed off and cut the cable I
think. OH, see the dirt on the left? That's the dirt from
the sweat of your hands. It stinks and needs to be cleaned.
