London has two types of schedule for buses and metro trains. On the most frequest services, the timetable says something like "every 6-8 minutes". Otherwise, it gives the exact time. With the former, the bus isn't going to wait if it's 'early', and waiting 1 minute vs. 5 isn't going to make much difference to your journey. Since even the most frequent services aren't so frequent overnight, you often see a mix.

Incidentally, at times I noticed the same slow pace of Berlin transport.
