Love the food, but am VERY disappointed that I was charged 1.50 for a refill, when every other time I have been to Which Wich, it was only .50  I don't understand how they can get away with charging different prices.  It seems to me that the price should be the same nationwide...and I have been to several different locations nationwide...all only charged .50 !  This will definitely affect my decision about how often to come here.
