White Castle review: Chhesburger sack on sign controlled by store 7.99 at 930pm

Last night I was driving by Veterans Memorial White castle in Missouri. On the signing board on their sign it said 10 cheeseburger sack 7.99. This is the sign where the store changes the board with I believe a stick go change letters. Its 930 pm. I pulled up to speaker and ordered this. They told me the sale was over yesterday. I repeated it is on your sign. To which Did I WANT SOMETHING ELSE? NO I WANT WHAT YOU ARE ADVERTISING. I ASKED IF THEY WHERE OUT OF HAMBURGER S OR CHEESE. NO JUST DONT GIVE THEM AWAY.
