I upvoted this because I hate it.

So take it back? If you put it back in the packaging and said “hey, this doesn’t fit where I want it”, they should take it back. I’ve never dealt with a store that wouldn’t.

I could see this if you ordered it online, sight unseen. Like, if the website were text-based and had no pictures and the description was “It’s a TV”. But you were at a physical store…
