I've been doing a little off & on work for a small motorbike repair shop. Their main
PC was getting ancient and it was replacement time, so we stepped through
anything they might fancifully need & picked out a new machine, just a Dell and a
small network upgrade (a new switch and NIC upgrade for another PC)
It came time to migrate everything from the old system to the new, and I'd set
aside a complete weekend with them to get this done. I arrived Saturday morning
to find just the brand new computer, and the old system nowhere to be seen.
They'd sold it earlier in the week. Everything. Their entire network included. Hub,
network cables, computer, backup drive, two printers, Sold.
They sold all of their BACKUPS.
They were lucky, the new owners were quite happy to get the backup tapes & drive
back (temporarily!), but it took an extra two weeks until everything was working as
it should be. Lesson number one for me: never presume the client isn't suddenly
going to turn around and do crazy things, sometimes you expressly have to tell
them what NOT to do.
WARNING: COFFEE IS HOT labels make so much sense to me now.
