One pet peeve that gets to me is something that's done on a lot of commuter railways and S-Bahns, the 10/20 minute schedule. The schedule looks like:
2:10
2:20
2:40
2:50
3:10
etc, when it should be like this:
2:10
2:25
2:40
2:55
3:10
This minimizes waiting and allows for frequent service every 15 minutes.
What are your pet peeves?
The escalators in some stations are way too long. Being on the escalator for more than 5 minutes is scary. These ones are always very steep too. Feels like I am being escalatored down to hell.
