Can I buy the stuff that is not for sale, please?

This wooden hand just sold in my booth.  I did not intend to sell it - I picked it up simply because I thought it would look cool to display some retro jewelery on it, which is how I staged it (and now I regret not taking a picture of it).  However, the customer wanted the hand.  So I gave in and sold the hand. 

 

Rather beat-up little table with a cracked back leg used to display my lovely typewriter.  But the customer did not want the typewriter, retro planter or vintage playing cards that it displayed, just the table.  So, I let it go.

 

 

Just the other day when I stopped by to rearrange a bit, a customer asked if the rack I just found to display linens was for sale.  I said unfortunately not.  She asked what price I would want to let it go.  I said $100 and watched her walk away.  I did NOT want to sell it and then have to find another display solution.  Was that bad?

 

 

Finally, several people have wanted to buy my booth sign.  I have declined.  The antique market owners have put a Not for Sale sign on it, which looks a little hostile perhaps. But it took me a while to make, and I am not a happy crafty person with paper and scissors.  Seeing how in demand it has been though,  maybe I should make some smaller versions using cool thrifted frames?

Is EVERYTHING in your antique booth for sale, or do you keep certain items just because they work so well displaying other stuff that you are *actually* trying to sell?
