I mean, I was in high school when the cell phones were largely flip phones and that one nokia brick that could probably survive being run over by a tank and at that point the rule was “nobody gives a shit if it’s in your pocket/in your bag and on silent, but if I see it or if it’s making loud disruptive noises from wherever you’ve got it it’s going in my desk until the bell rings”. That still seems a reasonable middle ground in my opinion. That way, it’s still accessible enough in the event of an actual emergency but not usable otherwise.

New England area checking in - currently about 5.90 at Aldi and like 8.10ish at stop and shop.

Edit: per dozen

I believe they’re already under a 40 day boycott

Honestly in a use case like family photos, redoing it every x amount of time is probably a good idea anyway so new ones can be added.

Guessing less about the sign itself and more about the heavy equipment/traffic obstruction involved in getting it down.
