Reply To: Lights on Shabbos and Thanking Someone for Doing an Aveirah on Your Behalf

For the sake of Shalom let’s take this in a different direction. Someone brings you food on Shabbos and there is no eiruv, do you use it? Do you tell them there is no eiruv? I think the best way is not to thank them, just explain what the halacha is in a seicheldica way.
