Atrocious service ! (Handling of child with celiac disease)

A child had a severe gluten intolerance and couldn‘t eat meat that has a sauce on it. After asking politely if it is possible to get the meat on the menu without the sauce, they refused. After discussing what kind of other possible solutions they can offer, the waitress became more and more spiteful and asked the customer to leave the restaurant, even if they already were sitting at the table and had ordered edamame and other things. So as some of the food was already served, the customer tried to make the best out of the situation and said they will eat what is already served. But then the boss came and asked them to leave. The staff are not willing to make slight changes on the menu for a child who has an allergy, even if they do not have to make something special and have only to serve the same as on the menu but without sauce.. In the end the child just ate the edamame and some rice from his mother's portion. Because they also refused to just give the child some white rice…

There was a Japanese speaking person in the group. So there where no missunderstanding in culture or language. Just very bad hospitality, which is very uncommon in this area.
