Burning Bridges. . .

You never know who your next boss will be, or even your next car dealer.
I've been burning bridges that ought not go aflame! (Weird phrase... I know)
Recently, I've been car searching for a reliable vehicle with low income. $1500.
A car was offered by a man I'll call Tom, but it was too old and in too bad of shape to be $1500. I told him so. He said "Whatever. Good luck finding a car for less then $1500 that runs good"
Weeks later, Tom's wife, I'll call her Rebecca, said they were selling it for $1000. Evidently they couldn't find a buyer. I said the most I could do was $800. She eventually hesitantly agreed.
Now the bad part. I found a different car that I'm interested in. I am looking at it tomorrow. I want to compare the two before I decide, but I'm afraid that Tom and Rebecca will be tired of my haggling and unsure behavior. I hope I didn't burn that bridge.
We will see soon.
