I’ll accept that full specification of which is okay and which isn’t, is going to be difficult.
Especially since:
“I want beer” (with a strong voice and expectant eye contact) --> Being clear about what I want and communicating that my mere wishes should implicitly be interpreted as orders.
“Bring me beer” (lowered eyes, end of the sentence raised slightly in pitch) --> Making an uncertain claim about what I want, with a supplicating request for action.
