The whole point of drinking a $5+ beverage is to enjoy the taste of it. That means, even if you use a straw, you're going to hold the beverage in your mouth so that your tongue and nose can experience it.

Straws really are only necessary with extremely elderly people, the sick and young children wherever one can't reliably lift the cup to their lips because of limited motor skills. Or perhaps in the USA where people drink 32 OZ beverages from a bucket that is liable to spill because of the waves caused by the ice cubes bobbing around in it.
