Yeah, I'll have a drink if it's free. Which doesn't happen that often these days, since I mostly fly Economy. One or two drinks is the maximum - I don't want to be drunk when I land and have to figure out a strange airport/public transportation system.
Most of my flights this year were early morning departures and no matter what time is, there's always someone having having a beer or two before boarding at HEL. I guess it's a "going on vacation" thing for some people, but I would rather have coffee at 6 am.
