I am very disappointed that you do not have a regular iced coffee, which is so popular all over the country! Please get a no-frills, just regular brewed coffee that is cooled throughout the day, to be combined with liquid sugar and half & half, then shaken, when ordered; just like starbucks and mcdonalds. Then you will get a valued customer back.
I recently traveled to Italy and fell in love with Italian cappuccino. I have always thought that Sheetz could compete better if it offered better espresso drinks. Please consider researching illy coffee, which is THE brand in Italy. I think it might even make you a serious contender with Starbucks.
