First of all, I am the boss of 3 companies so I only speak from how I would handle this since it is already in discussion.
Why does he respond at all if he doesn't address the one giant elephant in the room? Maybe its me, I don't get it.
I totally understand correcting problems internally and not posting what specifics will be taken on a forum however, if this were my business being scrutinized and I was involved in a thread discussing that you can be sure I would let my customers know loud and clear I am addressing that concern and take your opinions very seriously, not post lengthy statements about everything but the issue at hand.Just how I see it. But then again, i don't own a restaurant so what do I know.
