Went into pick up an online order right before a convention came in. They gave me the wrong order (right ticket, wrong food inside). I walked all the way back, told them the mixup, and they said they would remake my food. I waited 15 minutes and asked if it would be ready soon. The lady handing out online orders said I would have to wait until after all the other orders because they were busy. I asked why since my online order at that point should have been ready 30 minutes ago, and she said I’d have to talk to the manager. I asked her who the manager was, and she said he wasn’t here. I told her if they couldn’t prepare my food I can just take a refund, and she stopped responding to me but then loudly started talking to herself about how much she hated her job and how much she hates all the customers. A nice man then replaced my order. If you’re going to open a restaurant right next to the convention center, hire staff who can handle a mistaken order and have managers who can talk to customers when the employees are frustrated.
