I used to work as a salesman at a local retailer. I often worked nights alone. There was a security system that had to be turned on when I locked up at night. One night, when I was locking up the store, I noticed that the CCTV Bolton for the front door was broken. The video monitor in the backroom was just blinking a gray screen. I fiddled around with it but couldn’t figure out how to fix it. I knew that I shouldn’t lock up the store without having the it running because the store was located in a bad part of town. I decided to troubleshoot on my own. I got out the manual and followed the procedures to fix basic problems. After a few minutes I was able to reset the system and it worked. Sometimes it’s better to be self-reliant than rely on others to fix your problems.
