How often do you get your morning coffee outside the house?

On every other thread i see so many people saying they get their coffee at Starbucks etc in the morning, even while driving. I was wondering how common it is for people to buy the coffee they have in the morning or if its still more common to make it at home? I always make mine at home, as does everyone else i know, because i like to have a coffee before i leave the house and start the day. I mean ill have another if im at the trainstation sometimes, or just at a café, but its not standard or in my daily routine. It just seems so expensive to me to have it outside the house all the time, why do people do this?
