MICKEY ROURKE’s got a great Rx for turning waiters into gofers! Lunching at Cristoni in BevHills, “The Wrestler” star stunned his server when the guy asked if he could get him anything else, and Mick replied: “Yeah…can you walk down to the drugstore and pick up my prescription?”

Taken aback by the pushy request, the guy alibi-ed that his boss wouldn’t let him leave – but Mickey one-upped him and got the manager’s okay.

The waiter took off and was back in 15 minutes, looking none too happy as he handed Mick his drugs – but his eyes popped when the star dispensed his own perfect prescription for happiness… THREE HUNDRED-DOLLAR BILLS!

“Hope this made it worth your while,” drawled Mickey. “Yes, sir…anytime,” croaked the waiter.
