I’m not sure how you interpreted what I wrote as insensitive…
All I’m suggesting is that when there’s any chance of ambiguity in a life and death situation it’s probably better for all parties to choose the most cautious path. If a restaurant decided to specialize in a 100% nut free inventory then they could be confident telling customers they’re safe (but even then they can’t guarantee something wasn’t contaminated by a vendor/supplier) but any other restaurant should default to the safest option.
