Might require automatic light switches and plumbing fixtures so that no “work” is performed on the Sabbath.
Seriously....like the elevators in Israel stopping at every floor.
I accidently got on one of those elevators in my Tel Aviv hotel because the doors were open when I got to the elevators. After a couple of floors, I figured it out—and I was on 10...
But that’s only for one day.
Strange.
I did, however, notice that when I flew ElAl to Israel...we had Orthodox on our plane. When we arrived to Tel Aviv..the plane was littered with trash on the floor. I just shrugged and thought they weren’t to interact with stewardesses coming around to collect trash.
I think we have FReepers who are Orthodox who may can answer.
Which is no more silly than even some modern buildings not having a ‘floor 13’.
