Well, the young woman spoke true about Red Robin not shutting off their arcade machines for upon checking my score on Dig-Dug it was still standing. This time I took a little more time to peruse the offerings of the 'Happy Hour!' arcade machine.
Amidar, Space Invaders, Galaxian (Which I just learned this week is actually not a sequel to Galaga, it's the predecessor.), Pengo, and Burger Time were welcome sights.
After spending a dollar, I claimed the high-score for Mappy, second place for Burger Time...missed the mark by about 500 points, third place on Pengo, and second place behind my own score on Dig-Dug.
Plus I had a wonderful Gingerbread shake. Not a too shabby end to my work day.
