Hike sound like 1st date PC to anyone? I mean, it depends on the definition of hike but someone I barely know dragging me to an isolated place in the woods somewhere sounds like a legit way to end up being drug through the woods with a much higher probability than the typical coffee shop date.
Also, who doesn't have work-mances without deeper meaning? I always have beer after work bros and lunch/break dates with my coworkers but that has no meaning beyond. In fact, I've always had a strict rule of never shit in my own back yard. If I was so inclined as to date someone from work, I would not do so until after finding a new job.
