BS”D:
Agree with Kilo 1000%.
I have discussed this with my children when they were growing up. After hearing the Middos Machine song about going to a store, and the children tantruming until they get what they want, I asked them what do you think I would do if they acted up like that?
And then I told them. I would physically pick the child up, and remove them from the store (of course, we are not talking about doing so to teens (who don’t act like that anyway)). And I had to do it, once or twice. It is not right to the storeownwer that you are causing a situation in his store where people want to leave. I would even call it Karov to Gezel.
