Overheard in the Thai Restaurant

While I was waiting to pick up my Thai food, I witnessed a completely eye-rolling conversation.

Two women approached the counter of the restaurant and looked at a menu. One woman ordered a dish that has tofu, which prompted the waitress to ask if they want the tofu fried or not. The woman asked if the tofu is gluten-free. The nice waitress nodded her head and said yes. The second woman then asks, "Is it fried in oil? The same oil used for other things? Because then it's not actually gluten-free." The first woman then said to her friend, "just don't get it fried." The second woman continues to ask about the oil and the poor waitress eventually says, "yes, all same oil." 

I had no idea there are so many people with celiac disease.
