I’ve been ordering Americanos for 20 years. Espresso drinks became a very common thing around the time when Starbucks took off in the 90s. But it does depend on where you go. Diners and gas stations and some kinds of cafes and restaurants (especially in small towns) often only had drip coffee until recently, but these days you can get an Americano in many gas stations too. Cafes with baristas making espresso drinks is the norm in big cities and has been for some time.
