They ask everyone about dietary needs and if you say gluten they will ask if cross contamination is a concern. If you say yes, then they will go to the back and scoop out of an contaminated carton. The guy who scooped my ice cream asked all of these questions unprompted and got me some contaminated ice cream with a smile on his face. He even thanked me for my patience. Wow! So nice to not feel like a burden!!
