This morning I was coming up on a guy crossing a bridge, my water bottle (it's metal) was making some noise and he turned to see me and then started riding faster. I was doing 35kph already and passed him easily. He yelled at me that I shouldn't pass other cyclists and then passed me pedaling as fast as his bike would take him, when he did he yelled "How do you like it?".
I just let him ride on thinking himself the big man, I could care less about getting passed.
