I just finished my first day at my new job. What a satisfying feeling. In order to celebrate, my new co-workers suggested that we meet up at a local bar for some drinks. As I am new to the area, it took me a while to find the place and I was running a bit late.
Upon entering the bar, I walked into a man dressed all in black who silently hands me a slightly damp piece of paper before hurriedly disappearing around a corner. I stood there confused before unfolding the paper and became even more confused with what I found inside.
The lines seem like some sort of bar-code or an old-school punch card, but I can't make heads or tails of it. What does this strange pattern mean? I can't possibly join my co-workers before I figure this out. They might think I'm an idiot. Is there something I'm missing?
Could you help me figure out what this paper means?
