I had a supervisor like that once. Insisted we just zip all the code base from time to time and store the zip files in a folder. No need for source code, too complicated, don't have time for that, blablabla. At some point someone made some changes that broke a lot of things. It took two weeks to figure out what had been modified and then fix it. With a source control system it would have been very easy to find the source of the problem.

The same problem that I had many times, things that I would solve in less than a minute with git revert or tf revert, took hours to be solved.
