Nipping personal IT questions in the bud.
I've been a sole IT guy for a small manufacturing company for almost 2 decades and I frequently have to say "I'm sorry. I have to draw the line at getting involved with user's personal computing needs" It's always the response to someone sitting down in my office, pulling up Amazon on their phone and asking me "Which laptop would be best for my daughter?"
It makes me feel like an asshole because I'm genuinely empathetic and want to help folks, but most of these people have zero interest in talking to me otherwise.
The caveat of that is if it relates directly to their VPN/Remote workflow. But that's it.
I dunno. Had to tell someone that again this morning and I always feel kinda bad after.
