Small lesson update

I kind of had a little experiment going on with the signs I've been making. I decided to feature one item at a time. On my first sign I did a lunch menu with four or five items...no increase in sales. Then I did just lemonade: we sold all but two bottles. This past week, I did something crazy like Olive Tapenade, of which we had A LOT. I just found out that it sold out on Saturday! My hypothesis was right! WOO HOO!!
