ppl use 'San Francisco' as shorthand for 'San Francisco-San Jose-Oakland Metro Area' all the time.

ppl use 'Chicago' as shorthand for 'Chicago Metropolitan Area' all the time.

it happens in every single metro area in the country, if not in the world.

they're lying if when asked 'Oh, where in Chicago?' they say they're from the city when they're really from Burbank. THAT is a lie. or if they claim they graduated from Whitney Young when they really graduated from New Trier. that's a lie. but saying they're from 'Chicago' when they grew up in Wheaton is not a lie.
