Good question.
We went to a restaurant last night that typically has all 40 tables filled and a 15 min wait. Three tables filled. Wait staff sent home, owner doing it all. Not a good look. I left a huge tip.
We also went out to dinner last night here in Fort Lauderdale. The restaurant is very upscale and on the water. It was packed, not a single empty table. Except for the run on the supermarkets, everything here seems pretty normal.
