Potbelly is and always will be one of the best sandwich shops around! I don't have a problem with the food but with the service I received. I was the only one in the shop and there was only one worker I could see. When I went in she was wiping down the tables and told me she would be right with me in a second I told her it was fine because I didn't know what I wanted yet. She continued to wipe down tables for another 5 minutes which I mean okay I get it but I'm the only one in there can't you finish when I'm done ordering. Once she finished she then said she'll be right back and disappeared for another 5 minutes. At this point I was about to leave when she finally appeared again. She didn't apologize or anything just took my order. While doing so it looked as if she was annoyed. When it came to checking out I have their app and has received a free cookie so I mentioned it to her and she gave me a look and just stared at me. I had it pulled up and she grabbed my phone from me then told me to grab a cookie. I then grabbed my food and left. I couldn't believe a process that should only take maybe 5 minutes went on for 15 minutes. I was just trying to grab a quick sandwich after work.
