This is just a coincidence or this really the best crappy garage with high-advanced scam system..
Anything is possible and it will be hard to tell what actually happened or whether the incident is just coincidence. Leaving a door open or key in during a long service could drain the battery and if the battery is old or on its last legs then this could finish it off. Also check to make sure the battery cables are properly tightened maybe they didn't ...
That just means that particular circuit is an always on circuit and not switched by the ignition. When you reconnect the battery lead the computer is probably doing a power on test and as such some relays are being activated such as testing the fan etc.
