ROME — For most visitors to Rome, the city gets high marks for its monuments, food, temperate climate and laid-back lifestyle — the dolce vita.

Social media is rife with cautionary tales of ripoffs and swindles, often involving scenic — but unsolicited — drives past Rome’s historic sights or taxi meters that spin faster than they probably should.

It hasn’t been the best calling card for the Italian capital, especially as cabbies are often the first locals tourists interact with.

Which is why on a recent morning a few dozen cabdrivers found themselves in a nondescript hotel room taking a crash course in “courtesy, hospitality, language and excellence.”
