I will never completely understand human nature. Particularly the bit of it that drives supposedly intelligent, well-educated employees of an institution of higher learning to totally avoid three completely convenient and well-advertised modes of communication available for conveying their problem directly to the highly trained professionals available on site who are actually paid to solve it. Plus, there's the only marginally less convenient but additional option of "get your behind up out of your chair, walk across the beautiful and compact campus in the fresh air and sunshine to the office building which houses said professionals and have some probably pleasant face to face interaction.
But somehow, this is way too much trouble. Yet, somehow, they've got the time, motivation and bandwidth to get on the internet and "Vaguebook" about having an issue of some sort.
I have a revolutionary idea. If you have an issue with the setup of a lab machine, maybe try notifying the department responsible for setting up the lab machine in something other than the most roundabout way possible?
