As a general rule, cab rides not only lack drama, but are downright boring. There was an exception to the rule a few days ago in Sacramento, as reported by The Sacramento Bee:
A cab driver had a dispute with a rider over the destination at 20th and Q streets in midtown Sacramento on Saturday, according to a crime report.
The fare pulled a folding-blade knife, but no threats were made. The cab driver fled on foot.
The rider also fled on foot but not before paying (and tipping) the cab driver.
The rider was not found, police said.
Isn’t pulling a knife [apparently during an argument] a threat? Anyway, here’s the source.
