I think at some point, anyone who used a MS-based operating system at work may have indirectly stumbled upon MS Access. No matter how better other tools can be nowadays, there's no denying the fact that there are businesses who still have smaller MS Access apps that runs critical business processes. I have helped a small company (~9-10 years ago) who had an MS-Access based application where the source code was locked as well as the database. Took a while to unlock both the source and the database and up until today, that application is being utilized fully in their operations.
