Driver suspects sandwich shop posted sign in literal sense

On the way to work, a driver noticed a posting on a sandwich store sign that read “Visa, MasterCard taken here”. Driver imagined the expression on customers faces if sandwich shop was being literal because most shops accept major credit cards, they don't usually take them. Driver decided she wouldn't be using her credit card at that sandwich shop anyway; just something sketchy about the place and wouldn't doubt if they actually DID take credit cards.
