Machinists, mechanics, heck any blue-collar tradesman...we invented miller time. when the last deadblow gets put away and the timecards punched for the day, its almost impossible to avoid hitting a local dive for a few brews.
And if you're in-like-sin with the bar owner its even worse. I remember fixing a few compressor motors for a brew-pub...just simple bearing replacement...and if i so much as look in the window the guy hauls me in off the street to tie one on.
