Should we leave a holiday restaurant when an allergy question still has no clear answer?

The waiter has taken away the dish, then brought it back without the crushed-nut garnish. “There you are,” he says.

Niamh has a peanut allergy. She is on a weekend in Lyon with two friends, and has explained that she needs information about the ingredients and preparation, not simply a different-looking plate. She has not eaten it. The waiter appears to have understood “no nuts on top” and is now serving another table.

One friend suggests asking again. The other looks at the neighbouring diners and whispers that they should stop making a scene. They had all wanted to try this restaurant, and the kitchen is close to its last orders.

How should Niamh handle the unresolved answer, and what support would actually help from her friends? She wants to eat somewhere she can establish is suitable, without having to conduct a second negotiation about whether her allergy is an inconvenience.
