I think rules like "the DM always fires in person" are gone with the wind since things have really gotten down to bare bones. Along with a lot of other rules. For example, we're not supposed to be open for business unless a salaried manager is present. (We only have one. In order for this to be carried out, she'd have to work over 70 hours a week.) Or leads not being allowed to have a store key and a cashroom key. (Leads are the only managers in the store half the time, so have to have both now.) Corporate still talks about following policies as if they still make sense. In the stores we just do whatever we have to do to get by.
Well said, @O0e6XAT-2ouh. We are in the same boat. If we were to follow all the official rules, we'd never be able to do anything. They simply make no sense anymore. But to be honest, few things around here do nowadays.
