I know a lot of you guys battle competition, especially in the major cities. I suppose I have some, but I'm far more of a regular customer on the menswear side than any others I've seen. Anyway, in real life, I like to think of myself as a decent person. I will always let people in when they're trying to hop into a busy street. I'll make sure the person running to the tram/bus/subway gets on by hitting the button. One thing I've recently realized about myself is that this sane, rational person no longer exists when someone is in "my" section and looking at things that I have not yet inspected. I will say the most awful things in my head until the person hangs the item back and walks away. I'll take a look and see that it was nothing of importance and then feel like a fool.
No one else does that? Bueller?
I've developed a very Zen philosophy. If I'm meant to find it, I'll find it. If not...
But I prefer not to compare finds with other eBayers I know and encounter in stores. If they show me things I'd have picked up if I got there first, I feel jealous. There is one elderly woman in particular who looks for the same things I do, and I've been very jealous of some of her finds when we pass in the aisle, even though I know she supports herself with her eBay store and literally needs to make such sales, whereas I don't. OTOH, I've gleaned an aisle after she's gone, and found things I can't believe she missed. Fate, you know. I try to feel happy for her that she finds excellent things.
What I wouldn't be able to abide is a grail-slasher. I *have* heard of thrifts actually destroying valuable items upon receipt (usually by pricing with a fat black Sharpie right on the fabric) and then hanging them out for sale. This would be to frustrate the tag-switchers and the wear-and-walk-outers (you know, the ones who stuff price tags into purse and the pockets of coats; those items are never seen again).
