"I worked at a restaurant. Service can depend on which manager or lead is working that day. I can’t say this to customers, but if I could, most explanations would go like this: ‘The reason I’m giving you smaller portions is because the manager says so. Yes, you had bigger portions another day because a different kitchen lead was in the back monitoring, and they didn’t care. Sorry, we are out of that item; it’ll be 10 minutes. No, I can’t grab it from the other line. Yes, I know the other day we grabbed some for you, but the other manager allowed it, and this one doesn’t."
