7. Tip Regularly

Tipping is not a common practice in Brazil and many locals will not expect you to tip, however they will appreciate it. Tipping is only mandatory to hotel staff and restaurant waiters.
8. Lose Your Consumption Card

Many bars and nightclubs in Brazil will operate using a consumption card system, where each customer is given an individual card on entry to record food and drink orders. Patrons are expected to settle their bill before leaving, and not doing so results in large fines. So don’t misplace your consumption card during a night out.
9. Expect Only Beautiful Sights

Yes, of course Brazil is one of the most beautifully diverse countries in the world, but don’t expect perfection. Brazil is still a developing country, don’t be surprised when you come across extreme poverty, favelas, drug-torn cities and rude people, especially if you venture outside of the popular tourist areas. Don’t ever try to visit the favelas alone as they are run by drug lords and can be extremely dangerous.
