NO "Thank You"

Recently, a British network conducted a pole on 2,000 people living in U.K about whether to use a phrase "thank you" frequently or not and found the fact that 40% of them answered "No."
Instead of saying "thank you," they say "cheers," "cool," or "Ta (thank you); and some of them even use "Merci," "Fab," or "Garcias," which are not even English words.
Will they say "Arigatou (Japanese)" someday in the future?
