I was called over to computers by a new coworker. I asked a customer "What's the problem?" because I didn't hear what the issue was over the radio.
He had the audacity to scold me like I'm a child for my phrasing! I should have said "What's your concern?" or "What's your worry?" according to him...
I've been called stupid and useless and other things; I've had customers put me down with their master's in IT and other bullshit (lol); and I handled those without any trouble, but to scold me in front of my coworkers?!
It's at that point you just walk away and say "It's your concern then".
Respect given is respect due, idec if I'd get reprimanded by HR. But that's probably why I don't work in a customer facing role anymore.
If you want to be petty about this in the future - whenever they ask for help in the future. Go through every single step Ad nauseam. "Press Windows", "Click Search", "Type CMD", "Delete System32"
"You know the Delete function deletes things", "When you delete something it is gone forever" "Forever is a long time" "A function is a set of commands that do something when invoked" "You invoke a function by typing something" "You type by interfacing with the ~96 switch instrument in-front of you" "You can interface by using your hands that are attached to the end of your arms - that are somehow controlled by your peanut of a brain". "Some switches do things, like a function, do you remember what a function is?"
