They’re obsessed with hand sanitizer.
For whatever reason, Americans tend to have more preoccupation with germs than citizens of other countries and are quick to pull out the Purell at a moment’s notice. Check in almost any American traveler’s fanny pack and you’ll undoubtedly find a tiny bottle or two of the stuff.
Americans are stereotypically a cleaner group of people—showering religiously, never going without deodorant, and slathering on the creams, lotions, and perfumes. Whether it actually protects the user from global germs or just acts as a false sense of security, Americans aren’t soon to give up their hand sanitizer. They are willing to share though.
