It would be helpful for me if there was a way for us to customize our orders so we have the amount of something we want. I love your chef salads, but there's always so much ham on it. I'm not a huge fan of ham, so if it were possible for me to tell you to put as little ham on it as possible, it would make my eating experience more enjoyable.
I have a Sheetz card. I often order the same, customized orders. I would love to 'save' my frequent orders to My Sheetz card and then have them presented to me as a menu option by scanning my card. PS - It could also alert me to current and upcoming rebates like free coffee.
Make everything on the menu able to be completely customized. Having to yell back to the busy workers is too hard on both customer and workers and then you often end up with something on your food that you don't want/are allergic to/etc.
