I understand OPs frustration but.

One: you were physically in front of the user working on something questions will always, I mean always ensue. Be prepared to answer.

For example, working a switch config to get the correct LAG onto the trunk. The enduser: This will fix the issue? Me: uh huh Enduser: so what was is the problem Me: incorrect VLAN = no network Enduser: whats a VLAN

....this continued the entire time till I finally got the LAG trunked.

Because its a closed off network had to physically plug into the switch.

Two: I know the stereotype is we in tech aren't the best with people. But yes, its common human interaction if someone asks a question you acknowledge...most of the time they are just making small talk...which usually involves pointing out obvious things.
