WHEN ORDERING SOMETHING IN BRAZILIAN PORTUGUESE

In Brazil , it is common to go to the "padaria" ( bakery) every morning to buy fresh bread for breakfast. At the padaria , one can also buy other baked goods, as well as have a "cafezinho" ( strong black coffee) and eat a snack. Besides going to the "padaria" regularly, many Brazilians buy meat at the açougue ( butcher's shop) and fruits , vegetables, and greens at the "mercearia" ( grocery store). Needless to say, meats, fruits and vegetables are all available at supermarkets as well and buying any of these items at a local, smaller store doesn't preclude buying the same things at a different time at a supermarket.

Furthermore, Brazilians also buy fruits, vegetables, greens and other edible goods at the "feira"- the farmer's market that is generally set up once or twice a week year round in many cities and towns. About ordering something:

In English, the form Can I have....? may be used to ask for something politely. Note that this form of requesst does not translate literally to Portuguese. In other words, you cannot say " Posso ter...? " to ask for something. The form Can I have...? may correspond to (Eu) queria.... ( which literally translates as I used to want but which means I would like.....)
