Don’t F your workers.

Almost all of the BK locations are privately owned franchises. This is on that particular owner.

with senior supervision occurring remotely.

I consulted for one, decades ago. One individual controlled over 200 Burger King franchises in California and Louisiana, plus nearly 40 Chevy's franchises. The company was focused on profit and expansion, literally monitoring fractional pennies spent on pickles, lettuce, and condiments like ketchup, and earned millions.

Doesn't take much to imagine how all employees in any situation might be treated. This sounds like the work of an untrained manager, or, one under strict orders to just be a douchebag.
