In Manaus, as well as in the rest of the country, If you take a cab or go to a restaurant, tipping is optional.
In a cab you should only pay what the meter says.
In a restaurant they include a 10% service tax - which would be as a tip. Theresore, if you want to leave your favourite waiter something, it's up to you.
Then if you got bad service, you have to pay the 10% anyway, so don't feel like you're supposed to tip, specially because I think they don't expect it.
Still, in hotels it is more common people tip bell boys and stuff.
Other than that, tips are mostly if you fell the service deserves it.

poor...but very clean and very hospitable. respect the people and the culture. poverty is not choosen, being well of neither...opportunity does not knock on everybodies door. people get by here and take every job opportunity which comes along.
infrastructure in the north of Brasil has to get better to give everybody a decent chance. still 10% of the Rich own 90% of the Country and 90% have to do with the rest.
