For example, if you buy a new brand of maple syrup and you try it and don’t like the flavor. Should you be able to return it?

I’d never really thought about this but I watch a YouTube who was talking about a new brand of peanut powder that she bought but didn’t like the flavor of so she planned on returning. I didn’t think it was a big deal, but people were raising hell in the comments about how she shouldn’t be able to return it since she’d already opened it and it wasn’t a problem on the company’s end.

What do you guys think? Is this acceptable?
