Called today, caller ID said "Paper Roll Supp." Asked for owner or manager, I replied I am the manager, then asked when the owner comes in. I said he's in & out at different times, and if there was anything I could help him with. He then hung up.
Paper roll supply is likely the old scam: talk to you on the phone, use that as confirmation of an "order", then send you something worth far less than they bill you for, hoping you won't notice that you're paying $10 for one roll of paper..
