(colloquial) what will happen is a
matter of chance or
luck. A humorous variation of the
phrase you pays your
money and you takes your choice, suggesting that when faced with a choice between two
similar possibilities or alternatives, one might just as well rely on
luck. The
phrase comes from a rhyme used by
English traders with
market stalls / "Whatever you please my little dears / You pays your
money and you takes your choice. / You pays your
money and what you sees is / A cow or a donkey just as you pleases."
