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

"When visiting Maldonado, it's important to respect the local customs and traditions to avoid any cultural faux pas. Uruguayans are known for their punctuality, so it's considered rude to be late for appointments or social gatherings. Avoid discussing politics or controversial topics, as these can lead to heated debates. Uruguayans are very proud of their country and culture, so avoid making negative comments or comparisons to other countries. It's also considered impolite to refuse food or drink when offered, as this is seen as a sign of hospitality. When greeting someone, a kiss on the cheek is customary, but avoid doing this in formal or professional settings. Uruguayans value personal space, so avoid standing too close to someone during a conversation. Lastly, tipping is customary in restaurants and cafes, so not leaving a tip can be seen as rude," remarked another expat in Maldonado, Uruguay.
