Reminds me of a 1990s scam, can't remember if I saw that in a movie or if it did really happen. Some dodgy magazine advertisement for porn videos or something. Customers orders, write a check to a totally innocuous company name. Then the company claims they ran out of stock and issue a refund check, with a "porn xxx sexshop" company name, and of course no customer wants to present that check to their bank or having that name appearing on their bank statement.
