I agree. I think the problem is probably specific to school cafeteria companies, who likely don’t have the money or industry clout to compete for supplies with the large restaurant companies. The cafeteria companies also don’t have as much motivation to deliver in difficult circumstances, because their contract is set and they will get their money regardless of how students and faculty/staff feel about the food or service.
I personally haven’t seen any significant supply or service problems at supermarkets or restaurants, just sky-high prices across the board. That’s my perspective as a consumer. I know that behind the scenes many companies, particularly small restaurant companies, are absolutely scrambling to maintain food and service quality, and the owners and staff are exhausted.
I spent over a month this summer in a tourist area (Massachusetts Cape/Islands) and dined out A LOT, and had only one problem with food quality (waitress took the item off the bill) and two marginal service experiences (neither was a big deal, we still tipped well). Otherwise, our dining experiences were absolutely outstanding in every way (again, prices were eye-popping, but I expected that).
