My favorite liquor store an workers are very polite

Nice Store Friendly service fully stopped One Stop Shop

I stop in here sometimes to get my son a soft drink, and he wanted a mountain dew zero so I bought one and when we got home he took a sip and said it tasted nasty so I checked the expiration date and it expired over a year ago. So a few hours later I drove back up there to see if they would let me swap it out for a new one and they said since I had already left the store with it there was nothing they could do & they were just rude and insinuated that I didn't buy it from them even though I was literally just there 3 hours ago. I'm just upset because I paid for something that was expired & had to throw it away and then had to purchase another one for my son. Because of this and the way they handled it I will never purchase anything from this place again. It's just disappointing because normally the staff is really nice & I go in there all the time to buy stuff and they didn't give me a receipt but I think they hold onto the receipts for ppl that pay with a card so I even asked if they could check my receipt & I could tell them what I purchased so they would know which one is mine but they were so quick to write it off like I hadn't gotten the drink from there
