A certain relative of mine (insert joke here; I can take it) is a bigwig in a major jewelry company.
You have to make an appointment to get into the store. There is no waking in, just for this reason.
He predicts more and more stores will be moving to either this model or a membership model where you have to have an ID and credit card on file and pass a background check to get in. Akin to Sam’s club, but more more serious about not letting non-vetted people in.
Next time lock the doors…
