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

"In Minas, it's considered rude to arrive on time for social events. Arriving 15 to 30 minutes late is the norm and is seen as respectful. Avoid discussing politics and the military dictatorship period unless you are very familiar with the history and current situation. These topics can be sensitive and may cause discomfort or offense. Uruguayans are known for their love of mate, a traditional South American drink. If you're offered mate, it's polite to accept, even if you don't particularly enjoy the taste. Refusing can be seen as a rejection of hospitality. Personal space is not as valued in Uruguay as it is in some other cultures. Don't be surprised if people stand close to you during conversations. Pulling away can be seen as standoffish. Uruguayans are generally relaxed and laid-back, so avoid rushing or pushing for quick decisions. This can be seen as aggressive and impolite. It's also important to remember that Uruguayans are very proud of their country and culture. Avoid making negative comments or comparisons to other countries, as this can be seen as disrespectful. When dining, keep your hands on the table (but not your elbows), and only start eating when the host or hostess starts. Also, it's considered polite to finish all the food on your plate. Finally, tipping is customary in Uruguay. In restaurants, a tip of around 10% is expected, while in taxis, rounding up to the nearest whole number is common," said another expat in Minas, Uruguay.
