Subway locations in St. Charles, MO

Walked in this store at 7:30am and when I walked in the man behind the counter went in back. And he never returned to the front on the store. A young girl came out of the back with a bag of red sauce in her hands. She looked at me and never said a word. I waited a for about 10 seconds and then asked if they were opened. She pointed to the sign (neon "OPEN" sign) and stood there looking at this bag. I then said, I just wanted to make sure because you didn't acknowledge me. She continued to look and examine this bag. Meanwhile, there's a guy sitting in a chair in the back room within sight, that has not budged. Mind you, I am the only customer in the store. I waited and waited and finally realized she had no intention of waiting on me. I left and took my money to Quick Trip. Just as good, quicker service and probably cheaper. I picked up a Chef's salad for $4.29. I'm all about understanding that everyone has a bad day, but for three people to be working and I am the only customer.....there's something wrong with this picture.
