Do you guys do this too?

You know how there are those foods that when you eat them (with your mouth shut) they make a loud crunching noise, e.g. crisps, biscuits, apples etc? Well, I always assume someone can hear me so I start eating them really slowly (it kinda turns to mush in my mouth, gross I know). Do you guys do that too or do you not care? It's really only around strangers that I do that, not around my friends :)
