Because this story is related to Vienna and your post fits ...
Let me tell you about the viennese hotdog stand owner who had three microwaves running at all time, to heat food quickly. Open. Behind his back.
There was a glass in between the customers and him, shielded, but the pressure of the microwaves (heat, i guess?) could be felt through the opening, where he hands out the food.
I think the microwave is designed so that the radiation resonates in a cavity. Once you open the cavity, the waves spread in all directions and the energy drops off very quickly.
They are contained by front door, which has a metal lattice to create a Faraday cage. Of course they drop off in open air, but leaking microwaves are not safe.
No, it isn't, because I was there. My above post was clearly written in a way that makes it obvious to see that I was there. I've felt it on my own skin.
I don't know, I can easily believe that there are hot dog vendors in Vienna. Probably even one that has a silly name for English-speaking tourists like "Wurst Hotdogs!"

Of course it killed him eventually.
