It'll take a hour just to find a Walmart employee that works in the electronic section that'll willing to service you.
THIS, times 1000. Seems 8 times out of 10, the Electronics section is completely deserted at any Walmart I go to...even during peak shopping hours. Most of the time, I have to go to the front of the store and very nicely ask that they get someone to Electronics to help me. If I ask other employees in the vicinity of Electronics, they usually just put their hands up...."not my area man". I now just expect it will be a ghost town back there. Then, when I ask them to get something out from behind the locked glass doors, they look at me like I've asked them to balance the budget. My favorite quote from an employee when I asked if they had any PS4 PRO's in the back: "Dude, I don't even know anything about that". That was a coupla weeks back.
There are good people at Walmart for sure, but by and large, let's just say it's not often a "pleasant" experience in there.
