Appropriate investment
During my early career days I worked briefly at a startup. Their product could best be described as 'like ebay, but requires you to have large client software installed on your PC' - this in the days where 56k was the norm for a home user and a business might have splashed out on ISDN. This is just background to give an idea of how stupid the place was.
Anyway, they were absolute skinflints - student placement developers mentored by fresh graduates, old equipment etc. One of the machines had an ailing PSU where the fan would not start spinning unless you poked through the grill to get it moving, after which it would be fine. You can see where this is going right? one day the usual stick for this task had fallen off the desk so a hapless employee grabbed the nearest thing to hand and gave it a jab. He used a teaspoon... one *POW * later he was sat on the other side of the room and the PSU was at last in peaceful, smoking retirement.
Boss was incredibly angry that he'd have to spent £25 on a new PSU...
