I really appreciate what store owners have to go through to limit theft. Sad...And the idea of organizing the smaller, steal-able stuff behind the counter or right up front is a great idea. When I shop I will put my selected items up at the cutting table rather than carry then around, hope that helps them see I have no intention of stealing.
One of our LQS's is a nice sized shop. well organized by color, small items in eyshot of the cutting/register. I have seen the owner help many people and always was helpful, but not overly intrusive. Me? I did ask for help once, told her I wanted greens and purples, but no muddy greens. All she pulled out was muddy greens....I said again, same response. After about a few minutes she walked away exasperated.... She also sells machines and is always pushing them too. There is one clerk there who is very good, very helpful so I always try to get her if I need help.
