London is an exception, where "the City" (with a capital) is used to refer to a specific area within Central London, also known as the Square Mile. It's the main business district, basically.
UK: Those damn City workers and their 6 figure salaries.
2. Phone convo. better two kids that live in Marin:
Kid 1: "Let's hang out in the city this weekend."
Kid 2: "Sounds good, it's not like we'll have an issue paying the fucking $5 bridge toll to get there."
Sam: Alright! Let's go!
