Scouring the net I ran across this blog. It is called Gyopo Wife and she went to a Budae Chiggae Restaurant (military soup) and the ajumma working their just grabbed her child. Here is what she had to say:

The lesson learned while dining out was this: if you have a baby, beware of ajumas/ 아주마. The waitress dropped in the ramen noodles and then walked off with my baby.
