Arrived at Drive thru at 0730 on way to work and was told to go park while they prepared food. After 10 minutes I decided to check on status of my order, as I saw other customers getting theirs at Drive thru window. When I went inside, there was a large group of people who were also waiting. One man said he had been waiting for more than 10 minutes as well. The staff did not understand what was going on, and it looked very chaotic. They said we are making your egg mcmuffin now...5 minutes later they handed me a bag, and I went to work. When I opened up bag, there wasn't even an egg in the mcmuffin!!! Just brutal. The guy parked next to me was also waiting for 15 minutes and drove off without his food. Tried to call restaurant and speak with Manager, but no one answers phone.
