Once worked for a software company where we could run Linux on our machines if we maintained them ourselves and wouldn’t ask admins for support since they were only supporting the default windows installations. Right before Christmas new coworker joined, early twenties, got into a project that was apparently hard to get it set up locally, we told him get the project running and then spend time to configure your laptop the way you like it to be. Low and behold, he spends Christmas setting up and configuring some fancy desktop environment on Kubuntu, returns to work, shows off the fancy looks and within a week fails to get the project set up and everyone else in the project was using windows. So one week later he was back using windows and super pissed that he wasted like 5 days configuring his desktop. My heart is still bleeding for that poor guy :(
