(c) Permissive inference. If any person:
(1) conceals upon his or her person or among his or her belongings unpurchased merchandise displayed, held, stored or offered for sale in a retail mercantile establishment; and
(2) removes that merchandise beyond the last known station for receiving payments for that merchandise in that retail mercantile establishment, then the trier of fact may infer that the person possessed, carried away or transferred such merchandise with the intention of retaining it or with the intention of depriving the merchant permanently of the possession, use or benefit of such merchandise without paying the full retail value of such merchandise.
To "conceal" merchandise means that, although there may be some notice of its presence, that merchandise is not visible through ordinary observation.
