Mrs Cooke said: "At the end of the day it's about businesses having savvy staff working on the shop floor making sure they're constantly looking out for offenders and staying vigilant."
A zero tolerance approach was recommended, she said.
'"We tell our members their first port of call is to ring the police to deal with the matter."
