"Should you really ask, ... 'Is the Spirit of Yahweh impatient? Are these really his deeds?'" or "You should not say, ... 'The Spirit of Yahweh is not impatient. These are not really his deeds'". Micah is using a rhetorical question to scold the Israelites, who themselves are asking rhetorical questions to deny that Yahweh is angry with them.
Possible meanings are: these are real questions and the people really do not know if they are seeing Yahweh act, or these are rhetorical questions and the people do not believe that Yahweh is really punishing them.
