I feel like 'your wifi signal might be patchy' wouldn't set off this much 'do not go there' headbashing, but then we've been so few places with actually wifi that I don't know if my personal preferences would override that dangersense.
Not that that's actually ever happened, but...
I'm repeating to myself that ignoring it to walk past whatever danger line and find out is bad. Not a good or smart idea. Even if going home might be better for me than others.
