They are extremely slow but I deal with them because they are near home. Today I ordered a large pink slushi. When I got the receipt I told the young lady a mistake was made I wanted a large pink slushi not blue. She said tell them at next window. At the pick up window they had the nerve to say it was a blue lemon aid. I didn't want to hold the line up, but what ever happened to the customer is right when they are?
