How can a restaurant change their menu prices and post them on a paper taped to a door for a holiday? We went to king Buffet yesterday Valentines Day and normally they are a couple bucks more on weekends vs weekdays . However when we got to the door they had a paper sign posted saying... All Day Buffet 11.49... They never charge more than 18.00 for two ppl on a weekend... Is this legal to do? We didnt go in and several others drove off but who do you complain too...
