Don't kill that Grinder

[OLS]

I was getting that in a popular brand of shelled and roasted sunflower seeds. The
rocks are colored EXACTLY like a sunflower seed in the shell, and are some kind of pea gravel.
Talk about a shudder when you pour a bunch of de-shelled seeds into your hand and
pop em into your mouth and bite down on a ROCK! I complained to the company and
told them I was not suing or anything, but I wanted to alert them and help them to find
out how this was happening. THEY SAID they fixed it, sent me 5 dollars "hush money" and
things were great for a few more bags then I got it again the other day....crunch!
