What cultural faux pas should I try to avoid making in Hofn?

"When visiting Hofn, it's important to respect the local customs and traditions to avoid any cultural faux pas. Firstly, punctuality is highly valued in Iceland, so always try to be on time for any appointments or meetings. Secondly, tipping is not customary in Iceland as service charges are usually included in the bill, so avoid leaving extra money unless the service was exceptional. Thirdly, Icelanders are very proud of their language, so try to learn a few basic phrases in Icelandic. However, avoid mocking or making fun of the language as it can be considered disrespectful. Fourthly, it's considered rude to talk loudly in public places, so try to keep your voice down. Fifthly, avoid discussing sensitive topics such as whaling and politics unless you are well-informed about them. Lastly, respect the environment. Icelanders are very environmentally conscious, so avoid littering or damaging the natural surroundings. Remember, when in doubt, it's always best to observe and follow the behavior of the locals," remarked another expat who made the move to Hofn, Iceland.
