As Americans, we’re probably all well aware of norms like tipping culture and basic etiquette.

Here’s what locals from all over Europe had to share.

“Children in primary/grade school walk to school alone or in groups each morning, unsupervised.”

“I’m a Finn; we go to the sauna naked.

It’s normal to have seen your friends and family members naked.

It’s not sexual, nor is it embarrassing.”

“Everyone is sir/madam until you both decide otherwise.

Calling an adult you just met ‘you’ or by their name is a big no-no.”

“I have witnessed Americans fume at the way service works when eating food at a pub.

No one will greet you when you walk in or come to your table to take your order.

Find a table, read the menu, order, and pay at the bar.”

In particular, babies sleep alone in public places like restaurants or shops.”

“Finns value their personal space.

This includes both physical space but also verbal.

Do not sit next to anyone on the bus or sit if there are still empty seats.

This was a while back.

I am a millennial, so I’m not sure if it is still common.

We also had a party with soft alcoholic drinks at the end of elementary school.

Bars and grocery stores require an ID, though, if you want to buy alcohol.”

“Living comfortably without a car or a driver’s license.

Daily commuting is done by train, and the train stops in every other village.”

Then, the doctor or nurse knocks and comes in.

A friend said she was shocked not to be given a robe for her mammogram.

Just shirt and bra right off and let it all hang out.

They’re going to see your bits and bobs anyway!

It’s more efficient to not have that extra step in between.”

It’s anathema to them; it fries their brains.”

“Eating proper meals at school and not snacks.

I can’t imagine eating a pack of chips, pizza, or industrial slices of bread.

Lunches were cooked on-site and consisted of proper dishes like a restaurant.”

“Keeping a separation between work and real friendships.

Americans chit-chat at work and talk about personal things.

Currently working in the US and am a bit socially awkward at work here.”
