I was synchronizing all the check-out counters to the main server at a supermarket. One particular counter was out of connection. It was probably due to a faulty network cable. Someone managed to get me a replacement. I plugged it into the CPU and watched the connection lights at the switch. It blinked once and then went off.
We were actually on site due to some other issue. I didn't have a cable tester with me. I didn't have my cable connector crimper either. Maybe I could clean the contact points, but I didn't have any brush that could reach those tiny gaps. Looking around I saw a bottle of hand sanitizer by the main entrance.
I squirted some on the connectors of both ends. A lady nearby looked at me quizzically. I wondered what she was thinking.
I got back the counter, plugged in the cable and lo, the connection was on.
Sometimes all you need is some logical solution to solve a problem. Hand sanitizers contain alcohol, and alcohol cleans most kinds of surfaces of dirt and oil stains, etc.
Of course I remember McGyver... he taught me never to just let things go without looking for a solution, even if there are no proper tools at hand.
