Is the daiquiri a thing of the past?

The daiquiri was reasonably popular back in the 20th century although I must confess that I haven't had one for maybe 10 years. Last night we went out to dinner at a popular local restaurant. One of our party ordered a daiquiri. The waitress, a young lass in her twenties, did not understand the word, she had never heard of it. Okay, I can understand that. But the bartender had never heard of it either and he might have been in his forties. Maybe this is another indication of getting old?
