That's never happened, though I'm quite aware that it could.
It's happened already. We always award "the decision" to whoever comes first. Recently we had a Mario Party DS just before Christmas when everyone was looking for it. Two customers in the store at the same time wanted it, we gave it to the first person who asked. The second person was extremely ticked off and it's a little more complicated than I'm telling it now, but regardless, that's always the way I'd go. And even if she offered us a thousand dollars more it wouldn't matter. Regardless of what's more profitable, running a fair business is priority one.
