Burrito King Mexican Grill - Champaign

I really enjoy the food at this restaurant and I eat there multiple times a week. However, the person working in the food truck near Grainger library is a problem. I used to overlook his rude behavior, but today he refused to serve me because my bill was slightly ripped. He lacks manners, never responds to greetings, and overall seems indifferent. I often have to wait for him to get off his phone before he serves me. It's disappointing to have to write a negative review because the food is delicious and reasonably priced, but the service needs improvement.

The tacos and elote at this restaurant are delicious, but the quesadillas are terrible.
