I think you might be eating in the wrong restaurants. It’s not a problem I generally encounter, although I avoid sit-down chains like the plague.
No, its just the reality of restaurants.
My kid is a chef. He will bake "X" chicken pot pies, or "Y" regular pies, as part of this daily prep tasks. If there is an atypical run on them, the waitstaff will have to apologize and inform customers they are out.
Restaurants that regularly prepare food excessively, will soon be out of business. ☠
