It was the goodness of your heart..
I have done the same a few times, "just take them enjoy hope they work out for you"..
It is a painful walk away but good for the soul.
Now if your friend was dragging his ass twenty minutes before over something stupid and you see this guy humping them to the front check out..
Then i get pissed. My friend and i use to go thrifting and yard sailing, we are at this antique mall he's dicking with this old gumball machine wanting the key to open it up.
I'm like Dude he wants $300 what are you going to get for it $400 and then pack that thing? lets get to the Mexican Flea market stuff go's fast, twenty five minutes later he's got his key and gumball machine.
Get to the flea market not two minutes through the gate i see this Urban gaucho at this table whipping out cash surrounded by three Nikon f3 cameras with motor drives and a bunch of Nikkor glass and a couple Mamiya 654 medium formats..
I picked one up he says those are mine Bro!! OK chill, I was like looking at my friend Damn you Jim!! After he no doubt ripped this poor girl off with a baby in a stroller by her side i approached this clown and asked him you want to sell?
Clearly he knows nothing about photography but just to sell. Hey Amigo how much you want? $200.00 i say $150.00 Oh No, No, No! i walk away, Hombre $175.00? I say $165.00 Amigo, I have the cameras.. Then after i am happy cat my friend comes up, I know what he paid her for those i was watching, I say i don't want to know but you being an A hole in my book at this time are gassing up to tell me anyway... HE says $45.00 i punched him in the arm, you and you're freaking Gumball machine..
It was all she had for sale on a little table besides this old oil lamp,I would have given her $165.00 just because the situation she clearly had going on in her life. I walked back and gave her $20.00 for the lamp.
You can tell when someone is feeding you the BS and when they aren't..
Better stuff will always come down the road..
