Sheetz review: Zero service

This is the second time I have ordered something through the app and showed up to pick up when I was told to only to have to wait to even be acknowledged. The first time was over an hour. Tonight wasn't as bad however tonight I pulled up the window and saw some orders sitting on the counter but didn't know who they belonged to. One of the 2 people working looked at me and waved. That's it. No other service until 20 minutes later when the "supervisor" showed up at the window to hand me a freshly made drink... That I didn't order. When I told her what I was waiting for she said "oh" turned around and grabbed the bag that I had been looking at for 20 minutes and handed it to me. When I expressed my dissatisfaction she said "ok. There's only 2 other people here." that's it. No apology. No attempt to find out what happened. Nothing. I'm beyond pissed. My food is cold AND I'm pissed. Ridiculous. I hope this isn't how this location is going to operate. Completely uncalled for.
