How come please is not ok instead of thanks?

[forsilvia]

When an Italian person asks for something, he/she always uses "grazie (thanks)". We usually use "per favore (please)" when we ask a favor/help. Prego=you are welcome

[Thoughtdiva]

Very useful -thanks forsilvia!

So, you' d rather use "grazie" instead of "per favore" to ask politely for a favour in Italian?

[forsilvia]

No, when we ask a favour we usually say 'per favore/per piacere'

[tuess]

Okay, that feels/sounds better now. Thank you!
I just couldn't imagine a situation in that I would use this phrase.

[siebolt]

"A lemonade please" would be translated into "una limonata, prego" by me. In the original phrase I would have used a full stop: (waiter) Una limonita, (me) Grazie.

[nickruiz]

Or also "per favore" for please.

I believe that using "prego" when asking for something is very formal. And "A lemonade, thanks" is not so unusual for asking for things even in English. See forsilvia's answer below.

difficult, in real life you could catch it as please, but indeed this would create confusion when writing

[doubliouane]

I agree with that.

[Germima]

In British English the translation would be, ¨A lemonade, please¨ if you are asking for it.
¨Thank you¨ comes when you are given it.

In Australia we sometimes use "thanks" instead of "please" prior to receiving an item. This must be common in Italy also?

[bdavidfuentes]

I guess, in spanish we say thank you before receiving something too.

[hazza_h]

Shouldn't it just be "lemonade" or "a glass of lemonade"?

What's the difference between a lemon crush and a lemonade?

[GameWaiter]

'Please' definitely needs to be added as a correct alternative to 'thanks'.

[AssafShaha]

A lemonade, thank you ( for asking...)
