Just look at the number of little signs in this Del Taco fast food drive-thru. Four signs are visible but there were actually five, covering everything from new carnitas to very old, sun-faded promos for taco night. This is not counting the signs above and on the sides of the drive-thru menu. C'mon, Del Taco, If I am in your drive-thru, I am already a captive audience. You have me already.
