Where to place steam wand rag

I’m curious where you typically keep the rag after using it on the steam wand. I was originally taught that the steam wand and the portafilter rags are supposed to only touch the steam wand and the portafilter. They are set aside and are to be kept sanitary.

My previous jobs would have a special holder for the rag when not in use. While some would just leave it on the espresso machine. However my current job will go between a dish for the rag and just wrapping the rag around the machine.
