HUGE earner for the shop are the methadone script lids.
Swig the bottle out the back and nick a pair of £100 hair straighteners on yer way out, flog them for a score and go and buy a bag.
Some chemist shops in minty areas have their own " Methadone " swigging room, so the staff can keep them under observation at all time.
Also doubles up as a holding cell, if they have managed to lift something from the shop, until the Old Bill turn up .
