This has nothing to do with turbulence or safety, but rather the labor situation at DL. Similar thing happening at WN, where there is a labor dispute, so the pretzel and water service is often cancelled due to nonexistent turbulence. Meanwhile, I've been on moderately rough OO flights and they've made it through the F cabin 2 times on a 90 minute flight and done the snack basket...with smiles on their faces.
This problem won't be fixed on DL until the issue of FA unionization is resolved. Ultimately, I don't blame DL here, but Sara Nelson and her constant attempts to bring Soviet bread line customer service to the airline industry.
