Long ago in a tech company...
I get to my lab bench and guess what...the chair is gone. Somebody moved it into the fume hood room.. Few days later... Chair gone again! Bastards... :( Somebody took it and left it at a glueing station.
So... I tied a nylon cord to my chair.. Just a small deterrent.. Cord cut...chair gone! :( More annoying, somebody raided my tool drawer and used my own scissors to cut the cord...and didn't put them back..
Chain next??? Too extreme...So I just tied the cord together.
The chair borrowing stopped when there was about 6 knots in the cord. :) D from BC
