You're absolutely right.
It's those "little" jobs which have always been the real reason that biomeds need to be in-house, and on-site. To provide an immediate response, if you like.
We must also remain humble in order to carry out such work. Humble, but proud to be providing an efficient service ... whether that is appreciated by others or not.
Some things (many, in fact) cannot be measured in monetary terms alone (despite what the suits
may have us believe).
In passing, I'm wondering what any
of the service contractors would quote (if at all) for a 24x7 presence on site (a service that I myself, and others known to me, have provided in the past). And when I say "presence" ... I'm talking about shift work, carrying on with out-of-hours PM, whilst remaining generally available for whatever crops up, and all the rest.
