Cultural Tip
In Brazil the clitic 'te' is used in everyday conversation and sounds friendly. In Portugal, speakers often prefer the more formal 'lhe' when talking to acquaintances or in business settings. Also, Brazilians may add a polite particle like 'por favor' after the question: 'Que dia te serve, por favor?'.
