A taco but only on a sub roll...you already carry everything that you put on a taco and this way you don't have to mess with the shells...all you need is the taco meat...and they are really good. My family and friends enjoy them often and are great for taco lovers and sandwich lover alike.......(as long as it's good taco meat)
If I prepay for my gas purchase inside, the pump should ask me if I would like a receipt after I pump. Just like it would had I paid via credit/debit card outside.
Walking inside, then outside to pump, then back inside to collect receipt, then back out to leave is annoying and wasteful.
