    Placed a simple 1 sandwich order on the app for pickup. When I showed up my order wasn’t ready so I asked the woman working about it, no worries. She then tells me she doesn’t have any orders and gaslights me into thinking I placed the order at a different location. I pull up the app and show her the address is the right location and that I was charged for a sandwich. She tells me she has no orders and then begins clicking around on the POS system and then suddenly in my app it shows my order is cancelled. She continues telling me she has no online orders and never once offers to refund me or make me the sandwich I originally ordered. Then she randomly says something about how she cancels all orders that come through the app despite previously denying canceling the order. I am very confused as to how something as simple as ordering 1 sandwich through the app turned into this exchange. I left and had to inconvenience myself further by going to a different restaurant for what was supposed to be a quick to go lunch.

    Recently went to this location since I live nearby and the staff usually give great service and I know one of the ladies that is always great. But from my recent visit the guy making my sandwich was on his phone while taking my order, and he was talking to possibly a friend or someone he knew. He also had the station covered so I couldn’t even see my options and he kept saying “huh” because he was trying to talk on the phone. It was an older guy and wears chains, and Im assuming since he’s the only one there he can get away with it. But honestly ruined my experience.
