Dollar store customers are a different breed
Feel free to share your own personal stories, but here's a few out of MILLIONS that I experienced:
*Doordash/Instacart drivers and even a few customers putting water in their carts and asking if they have to take them out for us to scan them. We have the handheld scanners but they can't reach that far unless we stretch our body over the register. Gets annoyed at us when we tell them to put one on the register so we can scan them.
**Customers arguing with us over coupons that aren't being applied at checkout. Explaining how certain coupons work don't even help sometimes, and most of the time they ask you to take the item(s) off or void the whole transaction.
***Not as much of a common problem for me, but customers trying to refund gift cards despite the receipt saying all gift card and prepaid purchases are final.
