Taco Bell review: opening time

Have been here on multiple occasions around opening time. I understand that getting to work a few minutes late is a part of life. Unfortunately this is the 3rd time I've experienced this at the current branch. I got here 15 mins after the listed opening time and there are no lights on. Drove up to the drive through and nobody answered. Hours on door are listed as 7am, fifteen minutes after 7 and there's still nobody opening up.
