I gave this place three stars because they have a drive-thru and it is convenient. Normally, the food is fine. My average rating is due to the cashier. She is friendly at times, but she just won't bend. Every single time I come here, I ask if they can please just make me a Mulita. It is just a carne asada quesadilla with corn instead of flour tortillas. She refuses. I even begged her to just swap out the flour for corn in case she didn't understand and she said she wouldn't do it. I don't understand why such a small, easy accommodation can't be made for a paying guest when there is really zero extra effort involved. I'm not trying to be difficult; I am just allergic to wheat flour. Roberto's has no issue with this. I just like not having to get out of my car. I feel like this lady should be given some form of customer service training.
