Around where I live, the food overs are just shouted when they are ready, if the store is busy, sometimes it can be hard to hear the order number. Why not have the employees announces that "Order #xxx, is ready" or something like that.
I believe there should be some kind of an electronic board in the MTO area that states orders being made, orders undone, and orders on deck so if someone doesn't hear their number called or has to go out to their vehicle they can still see the progress of their order.
I usually forget my sheetz card in my truck - how about being able to enter you phone number in to use instead of your sheetz card?
It would be great if ALL toasted food was placed on toaster sheets or on the silicone pads that Subway uses.. Some sheets do this, others do not. Food tastes like ashes and cigarettes when I get it toasted.. This would be a good improvement :)
Sheetz should have carhops like Sonic. Your food would be brought to you while you pump your gas.
To make it feel like more of a restaurant, offer table service to take orders and deliver food.
The first thing I think needs to be addressed is the quality of the food being delivered. 3 out of the 4 items that I have last ordered were either over cooked or had items missing.
