So when I attended, this was never an issue - its been five years since I was booted. A bit before I woke up, a couple visiting us (middle America) from the deep South basically told me this never, ever was allowed in their hall. No 'priveleges' for a guy who chewed gum. I basically told them they were idiots for feeling guilty about chewing gum in the hall. They were taken back a bit at my frankness, even thought I was an elder at the time.
Now the Mrs. is pissed because some new CO basically stated chewing gum in the hall was some sort of giant sin to the big Jehoopla in the sky. I rarely if ever engage her on JW matters these days, as its become a live and let live environment on the home front. But I couldnt let this one pass so I told her its just another control mechanism from the WTBTS, or from the CO if he has some sort of personal agenda. Its really getting to her...so I'm happy about that. It would be hilarious if she slowed down further in her attendance because she can't enjoy Orbit while listening to the drones at the KH.
Just curious about attitudes toward gum chewing in your area.
