This morning I called the Home Depot lady in Atlanta and explained the latest wrinkle. I was pretty distraught. She was very nice as always and said she'd look into the situation and get back with me.
A little after 3:00, I got a call from the contractor who will be doing the drywall. They wanted to come in next Tuesday. I told her I'd talked to the kitchen designer over the weekend about putting a strip of molding beneath the bar counter where it sits on the half wall. (The designer recommended it.) To back up a minute, two weeks ago when the drywall guy came here after the cabinets were installed, he asked whether I would need such a molding. I told him at the time that I didn't know. So the drywall guy does the moldings, too. Anyway, I told the contractor today that perhaps they should hold off doing the drywall and molding work until the counters are installed, since the bar counter will have to be in place before they can add the molding. She said she'd talk to the drywall person and call me back. Sure enough, they'll come in and do this work after the counters are installed. I'll let them know when that's done.
An hour or so later, the District Services Manager called about the counters. Notwithstanding what I'd heard yesterday from the counter people (and I mentioned I'd got "riled up" over it), he assured me that the counters are coming along fine. Maybe they're coming along fine as of today when someone took some action, but that's OK, too. Along as things are moving along, I'm fine.
P.S. At the beginning of the week, I primed and painted the wooden brackets that will support the bar counter top, so I'm all ready to go here. (Photo shows brackets sitting on the half wall, atop which an arc-shaped counter will be installed.)
