There are "straight or narrow" "agencies", dishonest individuals, or fraudulent businesses.  All or none have a "problem" or "solution".

Which should or shouldn't be implemented?

Whichever sows the most harm or reaps the least damage.  Should a "business" wish to conduct "shady dealings" that escape attention or notice, they want only to "suggest" their "clientele".

This is never practiced by "jewelry" chains or stores.  Neither by any "storefront" where valuables are on insecure display.  If an individual is "only looking" they may feel "pressure" to "hurry up" or "go away".

Backward or "exit the premises".
