I'll tell you how stupid customers can be. This happened on Christmas Eve. We have a new car sale and it ends on Dec.31st. If some one commits to buying one of our new cars we will show him / her the invoice, yes the actual invoice we have from the mfg, and add $1.00 to the price. A customer and his lovely wife drove the car and wanted to negotiate the price.

I told him because we advertised the sale we can't sell it for more than the buck over

but he was insistent he be able to barter. The fools wanted to pay us less than what we paid for it.

They left saying they had to think about it and would probably be back after Christmas. Ya right.... as if customers don't lie.
Psssssst....... Buyers are liars.
I've been saying for years that people just don't know a good deal when they see one.
