I tried to make Amazon returns for 2 small separate items today. I had the barcode, no other messaging that these must come packed, and the exact same items have been accepted without packaging before and very recently as in like 2 weeks ago. Owner (in front of a somewhat busy time in the store) tried to tell me I must be remembering wrong or I must be crazy because there is no way they would accept them. #1rule of customer service- don't imply your customer is crazy. Big mistake.
