@ShopperGirly, I would think they should based on the shop window hours. 
However I've done 4 so far with 2 between 2-3PM and 2 between 5-6PM, and none of them had any pizza. Three were Self-Serve with no staff available and 1 was like a mini (pizza store) with 2 workers who told me they were out of pizza. So you take your photo of the empty pizza case and buy something that will be reimbursed up to $3.00. I got their store brand 6 pack of Microwave Kettle Corn for $2.99 and $3.49 as well as some chocolate. I'd suggest having something in mind in case there is no pizza so you don't spend more time than necessary looking for something to buy (unless you happen to want to look around).
I have a location tomorrow that will be after lunch so we'll see... I also have 2 locations on Tuesday that I'll do right at the beginning of the shop window so maybe I'll finally get some pizza.
