I could, though for how often I'd have to do it it would be a significant hassle. And I suspect chances are they wouldn't be able to find the items anyway with how messy they seem to be with inventory management and they are probably misplaced and rotting in some obscure spot where one day years from now they will be 'discovered'. Plus don't have any faith that seeking out a manager every time this happened would actually effect any change in the end. For me at least it's night and day between Walmart and Target for example asking to check for (and realistically find) something in the back.
Yea that's not very good advice. Managers are usually more incompetent than the normal associates. The one time I had asked for a manager during the start of the new 2ds xl craze when stores were showing 3+ in stock I waited 10 minutes for one to finally come just to be told "we don't have any". I asked to for him to check in the back, he pulled his mask down, and said "if they aren't on the floor we don't have any".
So that was a waste of time.
I just did this last night. This guy in electronics refused to sell me more than 1 copy of any game. So I purchased 1 of each game I wanted then I went to customer service and asked for a manager. Explained I wanted to purchase more games but the guy said I couldn't. Manager went back to games with me and let me get what I wanted. Sometimes you have to be persistent to get what you want. Not in a dick way either, always be nice until it's time to not be nice! (quote from Roadhouse, I couldn't resist) lol
In this case, I dont blame him. Why do you need two copies of the same game?
