Arrrr, me hearties. *cough* ahem, not September 19th yet. You see, if you happened to have a Long John Silver's near you that store shall be celebrating "Talk like a Pirate Day".
I know my store is giving away free pieces of fish (maybe chicken too, I double check) to customers who dress like pirates, and employees have been encourage to cosplay pirates as well. However, based on this I am guess each store will have its own deals.
