When you are doing dijkstra every 5 fucking second trying to pass the guy in front of you while walking.

Try A* ;-)

Then try the RIP Protocol.

I so hate it when people walk in the middle or the road sometimes as if no one might come from behind them.
Even worse if they are a group of people and they basically are blocking the way.
Super annoying on narrow roads!

Ahhhhh please whenever possible make sure you're giving space for anyone that might be coming from behind you.

Slow walkers should stick to their lane.
