Here's some remarks I've made while living in Munich, Germany (vs. in Finland). I made a similar list in 2004 in Austria.
Here we go.
- It's very customary to not be able to pay with a credit card. One needs to carry always cash. Sometimes just the local debit cards are valid, like in Ikea
o_O
- Even with high traffic, everyone obeys the zipper merge (Reißverschlussverfahren) which works nicely
- There's adults safeguarding the school kids way when they cross roads, even in cross roads with traffic lights
- In winter, kids (and parents) don't seem to use gloves (wtf). Also proper outdoor trousers are not very common for kids, except for when skiing.
- In skates, most people have ski boot style bindings instead of laces
- In winter, kids use wooden sleighs instead of plastic sledges
- European health insurance card (EHIC) allows for both medical and dental care in acute situations. And, the patient does not have to pay anything, not even for prescribed medicine!
