This one takes place about 8+ years ago, not long after I'd landed my first IT support role, but figured you guys would appreciate it anyway. While out on a visit to my local tech retailer to pick up a replacement part for a personal device that I owned at the time, I made my way into the store & darted over to the technical support desk area for collection.

The queue was short, just myself and the middle-aged guy on front of me speaking to the employee behind the counter with his laptop out on the counter. I stood there for a few minutes, minding my own business headphones in not really paying attention to what they were doing.

Ten minutes or so had passed and they were still chatting/ working away on this guy's machine so I figured while I'm here I'd go look around the store for a bit, kill a bit of time then wander back over to the desk once they'd finished doing whatever they was doing.

After completing a lap of the store, I re-joined the queue behind the same guy at the counter. After another short wait it was starting to become apparent that they had clearly been there for a while, so decided to pop one of my headphones out & listen to what was going on?

Then after listening I chimed in "Hi, sorry to interrupt but what problem are you having?" The elderly gentleman responded with "I bought this laptop a few days ago with a mouse, and I keep accidentally catching the trackpad/ keeps interfering with the mouse & we can't figure a way to turn it off?"

To which I replied with "Have you not tried the shortcut on the keyboard, you should be able to press FN + F7 or something like that & it will disable it?" The tech behind the desk then looked at me, then back down at the keyboard on this gentleman's laptop & then pressed said key combination then within about 3 seconds the employee responds with "Oh!? That done it"

The gentleman then turned & looked at me and said "Oh thank you, you've saved the day! we'd have been here all morning trying to figure that out, I think you should be working behind the desk instead!" Which I simply responded with "oh, it's nothing it's just one of little things you learn. I do this sort of thing in my job a lot"

I looked over to the employee behind the desk, he seemed a bit embarrassed about the whole thing & I kinda felt bad for him at the time, such a simple thing but we've all been there! At least he'll never forget it
