A scam devised by gypsies which involves a "paver" stopping by a house or business stating "I have some leftover asphalt from a big job and I can pave your driveway inexpensively." They either do a really poor job, jack up the price that you agreed to, or do the job after you say no and demand money.
John calls his Boss: "Some weird looking smelly guy is asking if we want him to pave our driveway? He says he has a bunch of leftover asphalt and can do it real cheap."
John's Boss: "NO NO NO NO NO!!!! Tell that disgusting gypsy to take his paving scam elsewhere!"
