I mean I’ve definitely seen signs at checkout lines at grocery stores. I’ve also been asked when buying large amounts of gift cards what my reason for buying them was (in a very kind way, I would add).
Yeah, I worked at Walmart for a bit and we were taught to look out for weird situations with gift cards and politely ask what the customer's plan was. If we thought they were getting scammed, we'd get our manager involved to talk to them
I don’t think you understand how determined the buyers are once they’ve been convinced by the scammer. I used to work for a major retailer that had signs at the register AND messages that the customer had to accept on the signature pad confirming they didn’t believe they were being scammed before going through with the purchase.
Additionally, my team was instructed to call me over any time they had a customer who they felt was being scammed to try to talk to them. Sometimes, I was successful, but other times I wasn’t. There is still one guy who goes in weekly to buy $500 of various gift cards for his overseas “girlfriend” on WhatsApp. I tried talking to him multiple times and he became increasingly angry at the conversation. I just had to accept I couldn’t help him.
