Wow, I wonder how new this system is - I've been to Whole foods in the last 3 days and it looked nothing like that picture. I wonder if these images are extreme cases that happened after 1 strange situation, and the article makes it look like a nationwide epidemic.
- Distributors have changed delivery schedules to work around New Year's Eve and Day.
- There's a large increase in demand for produce and some other ingredients (resolutions)
- Employees at the store and regional level take a few more vacations than usual, since we aren't able to during much of the holiday season. People also tend to plan the hell out of ordering for Thanksgiving and Christmas, but relax too much by New Year's since they figure crunch time is over. This is made worse by the relatively short tenures of most store buyers, since they either move up or quit relatively quickly.
So I would say there probably was a nationwide spike in out-of-stocks spread out over a few days. But it isn't really because of OTS.
