proven right...

Just like clockwork!  This morning while I was picking up some printouts, there were a couple of guys standing around the printer waiting for a big print job to finish.  After only 1 hour and 5 minutes of work, the one turned to the other and said "shall we go for a smoke?  Should take about that long for this to finish" and the two of them disappeared for 20 minutes…  I rest my case.
