I’ve been that guy at a computer store. Had already found what I needed on my own since I was quite familiar with the store and was browsing a different isle to look at the shinies. Overheard a customer ask a salesperson what the difference between product x and y was, which were marked very similarly on the box but one was something like 30-50% more.
I noticed the salesperson become quite unsure of what this specific technical difference was, so I added the quick TLDR paragraph of what the generalized difference was and what words the manufacturers use to differentiate them (since there were several product pairs that matched both classes elsewhere on the isle).
Customer says “oh ok that makes sense”. I forget which one he decided on (I think it might have been the more expensive one kek), but the salesperson put his commission tracking sticker on the selected box and the customer wandered away, hopefully happy. Salesperson turns to me sheepishly “Um… I guess you probably don’t need help?” I responded “No, I’m just browsing, but do you want to put your sticker on this gizmo I found in the bargain bin over there?” He seemed happy with this arrangement, adds the commission sticker, and we part ways.
…did I inadvertently make a pact with a different type of fae?
