Tons of small businesses are shut bec the owner is in Miluim. - I needed a locksmith this week. My wife went downstairs to get my son from someone who was dropping him off, and she locked the door behind her so that my 2yr old wouldn't open the door and run outside. When she came upstairs - the lock was broken, and she couldn't open it.
We waited close to three hours for an available locksmith - with a 2yr old and 1yr old stuck inside.
In the end yedidim found someone who basically broke the door down.
