Same stories all the time with the drug seekers.
I caught one patient actually pricking his finger to put blood in his urine specimen to make his Percocet-requiring-kidney-stone story all the more believable.
I give them a information sheet with contact numbers for the local substance abuse help centers during the visit.
I also reinforce to my staff the need to collect at least a partial payment up front for cash paying patients, especially those with the red-flag chief complaints.
