Joseph:”If the psak is you can’t keep your Amazon store open on Shabbos, how’s that different than the storefront with the non-Jewish Saturday worker?”
ZD: “If you use Fufillment by Amazon, you cant close it”
ZD, if your statement was a response to Joseph’s statement, it’s not a good response. If it’s assur, then it’s assur, and you are not allowed to open it in the first place.
Note: I have no idea if it’s assur or not – I am just noting that the response is not a logical response to the premise.
