Taco Bell review: response time and customer service

Sub-par: 8-10 minutes per car at the 2101 Rosa Parks Blvd TN location. Each time I've gone through that line on my break, I've been late coming back to work. I understand taking TOPS 5 minutes per car, I immediately go to my car, takes less than a minute. No customer service skills, orders messed up or wrong entirely. Quickly losing a customer here
