We in Australia, reminds me of the very old and true saying:
'You can't have your cake and eat it (too).'
You can't have your cake and eat it (too) is a popular English idiomatic proverb or figure of speech. The proverb literally means "you cannot simultaneously retain your cake and eat it". Once the cake is eaten, it is gone. It can be used to say that one cannot or should not have or want more than one deserves or is reasonable.
