Yeah I get that.

I'm leaning towards you in this case, since it's so strongly associated ice cream <-> dairy, but nowadays there are all kinds of frozen ice cream-ish products. But yes, a sign is often enough. Not always, since if the allergy is severe enough, you also can't risk the server not to use the same spoon as peanut ice cream, or a separate spoon but rinsed in a bucket with the others. And it's enough with one slipup.

So, for me, I take it as a positive signal that such a place is likely more aware than other places, and is more comfortable with my probing questions. Many places aren't, and yet others try to assert something they actually can't live up to.

It ain't easy, being highly allergic.
