Hello Rabbi,
I have a few questions.
- It is possible to order a pizza or any food from a non kosher restaurant (following your instructions) before Shabbat to arrive for Shabbat dinner? Nowadays it is possible to program a delivery through delivery apps and you don’t even have to check your phone or anything and the payment is done through the app automatically. I think the main concern is if it is cooked once Shabbat started.
- In a place with an Eruv. Can I grab the bus to go to a free museum or to go to the synagogue using a prepaid bus card? Can I pass it through the scanner when entering the bus? Can I request the bus to stop?
You can order on a programable delivery app to receive a Pizza on Shabbat evening or even Shabbat morning. You are not asking them specifically to cook for you on Shabbat. If they cook it late Friday afternoon, and then warm it a bit before delivery, you wouldn’t know the difference. It is not much different than going to a kosher hotel for Shabbat. They’re doing all types of things in the kitchen, but as long as you don’t need them to do it for you on Shabbat, you’re good.
With regards to the bus in an Eruv… First, I recommend everyone read the Torah Talk entry regarding Boats, Buses, Trains, and Planes. https://kashrut.org/project/can-you-ride-a-train-bus-plane-or-boat-on-shabbat/
Second in response to your questions:
Using a prepaid card works. Going on the bus is perfectly fine. passing it through the scanner is not any Melachah that I’m aware of, so it is also fine. Stopping the bus at a stop where he is not going to stop except for you… is ok, because again there is no Melachah that he is doing. Even if driving the bus is Havaarah (Like Lighting a Fire), however stopping the bus is not Mechabeh, because Mechabeh needs a Pesilah (Petilah = Wick) in order to be a Melachah.
So in summation…Yes, Yes, Yes, Yes, and Yes. Enjoy
