My co-workers & I (over 70 people spread out over 4 shifts) order Riggtown A LOT. Yesterday, 7 of us placed an order totaling over $65. We could hear the owner in the background when we called to place the order actually sounding annoyed because we always ask that they write on the food wrapping what it is so we know which food goes to whom. The food arrived and they messed up my one co-worker's food AGAIN for the third time in as many orders. He called them. All of our phone calls are recorded and I listened to his call. When he called to complain about messing up his order AGAIN, he sounded angry. He didn't curse or call anyone names, but he was frustrated. The owner immediately went on the defensive saying "Calm down! Calm down! If we mess up your order all the time, then don't order here anymore! Now, do you want the replacement wrap or not?!" He said he did and the owner said, "Fine..." and hung up. Ten minutes later, the owner showed up and was let in to deliver the correct order. He walked up to my co-worker and began to berate him for saying they always mess up his order. This was in front of all of us. He just began yelling at him. It was the single most terrible display of customer service I have ever witnessed. Needless to say, he was immediately told to leave. An email went out to all of our 70+ employees telling them of the incident. Our work is a 24/7 operation. Riggtown delivered to us about 5-6 times a week between all the shifts but will no longer be welcome at our place of business.
