“No need to have a maven present.”
A couple people informed about food allergies is all that’s needed. The law puts the onus on the diner to ask, and the restaurant has to have someone who has a clue. About food allergies, and they are in the business of providing food. In a world where lots of people have food allergies.
And they have to be there ALL the time... if one of them sicks out then what?
No, do not ask restaurants to be nannies. The default answer should be “we don’t know.” And it’s the allerginuts who have asked for that.
