once and a while I'd take a bite and there would be some sort of minuscule but noticeable hard... thing, I don't know what. Just a noticeable tiny bit of grit.
Most likely a stray bit of bone.
I hate that shit too, I come across them once in awhile in processed meats, including and especially prepackaged bbq rib sandwiches.
Ahhh okay, that makes sense. I'd get it in Bologna too.
