Today in the tech store I asked an assistant where to find the CAT6 ethernet cables.
He said he didn't know and ended up in asking me for technical support.

At least he admitted he didn't know instead of trying to sell you "something".

I sometimes come in a consumer electronics store to buy a cable, but one question and they will get ten people and still are not able to answer the question. In the meantime half an hour has passed and I give advice to customers after I heard them getting bad advice from the salesperson.

Like getting a PS4 for a 9 year who only has a small 5 year old tv. The salesman recommended the pro because it was way better than the slim while the slim had a 100 euro discount...

Or sometimes telling full out lies to make sales which I feel the need to correct.

@Codex404 I hate when I see people buying incredibly expensive Computers in stores instead of buying the components and building it themselves, but what can I do. The majority just doesn't know about that stuff and just need a working solution for them. Just lately I've also seen someone buying a copy of WinZip.

Had something like that a while ago where I went to a home improvement store to get some solder sucker (old one got its tip clogged, and I didn't know at the time that you can melt some solder and suck it in to unclog it).. Apparently it's a "specialist tool" that you can't possibly get in a home improvement store (that nonetheless sells cheap & crappy soldering irons). 4 employees were in that store at the time, and 3 of them didn't even know what it is and asked me to give them a picture from Google, and the fourth one told me that "specialist tool" thing. Needless to say, I decided to not visit that store anymore. Eventually I got my "specialist tool" from a different home improvement store though :)
