This. I can't like this post enough.
Don't forget about that lady that can't decide on a table-top frame, and decides to pick another and place the other one in it's place, but decides to pick another and place the other one in its place, but decides to pick another and place the other one in its place, but decides to pick another and place the other one in its place, but decides to pick another and place the other one in its place, until you, the person cleaning that aisle, suddenly realize that as you're doing so, you're backtracking the trail of a madwoman.
Or when a customer comes up wanting a picture framed and you show her a frame and she wants a different frame and maybe not that color can you get it in another color and what about mats oh I only want one mat I think can you shrink it down I don't want it to be expensive and oh ok that looks good now what's the price OH MY GOD THAT'S OUTRAGEOUS AND THAT'S AFTER THE DISCOUNT that's just INSANE I think I'll just put it in a crappy Chinese-manufactured frame from here on the floor thank you very much sir goodbye.
Yeah, I work in framing.
