Fate's a waiter

Another phrase that means "Justice has been served." Probably derived from a joke involving the definition of "served" and exactly who the server would be in this case. In any case, Fate seems to serve Justice in this manner.

syn: "Fate's been a waiter"
ant: "Fate's no waiter"

I see that your purse was returned to you, it's obvious that Fate's been a waiter on this one.
