Well, that's just you not empathizing with them. Chewing is not too different from walking. Imagine if someone told you they think your gait is too short, and could you take longer steps. How long would you be able to hold your affected gait before going back to your optimal gait?
I've had near violent reactions from people when I said "I can hear you chewing." I was a mild and meek kid, and this was after they acknowledged the noise they made.
Any subconscious behavior has to be controlled with a lot of effort and focus to change.
Almost no one I have ever met has changed a subconscious behavior, just because I asked in a certain way.
Walking can be met half way, or I can adjust _my_ gait to match there's. There's no equivalent to an irritating behavior.
