Think it depends where you work
When I worked in a company big enough that I didn't know anyone around me at the office, I only said hello to the receptionist
Whereas at companies where I know and work with the people in the office, of course we say hello to each other - we even hang out at each others houses sometimes

I can't believe Dr Pepper never had the "what's the worst that can happen" advert in the US, it was their whole thing here for years and they even put it on the bottles
