Well before use

If you were a lawyer, how successfully do you think you could you argue that the instruction to shake a can “well before use” was ambiguous, and in need of clearer definition?

Is it “Shake well before use”

or

“Shake well before use” ?

Could you argue the latter on behalf of a client for whom unfortunate consequences had resulted from not shaking immediately before use?

You be the judge.

No, I’m the judge. You be the lawyer.
