Review of Snap Custom Pizza

I had a poor experience. I walked up to the counter and told them that I had a gluten allergy. They questioned making my food "off the line". I order a pizza with herb butter, grilled chicken and peppers. I watch the gentleman putting my pizza together grab butter right of the line full and a flour covered area. I had to asked three times for a manager before getting one to help me. The manager informed me that herb butter wasn't available off the line, so he remade my pizza with olive oil. He was apologetic and didn't charge me for the $2 fee for GF. However, I'm not sure I'll go back.
