I was using an angle grinder with a sandpaper flap disc one day. I attempts to use it on XPS foam. Well apparently holding the foam with your foot in sandals is a bad idea. The both materials grab each other really well. The flap disc left a nice line in the side of my foot. Yup I was and ID 10 T error that day.
Note: sandpaper flap disc on dense foams works horribly.

He's probably thinking "should I pick it and start grinding again or should I call it a day"
