Do you never step out of a store without making a purchase in your real life? Even when I shop for something I want or need, often I leave without buying for any number of reasons. Wrong sizes, colors, styles, prices, quality, just not feeling it, etc. If I bought something in every store I ever stepped foot in, I'd be buried alive under merchandise! I never feel guilty for not spending my money, regardless of whether the sales people have done a good job or not. I only spend my money on things that I want.
