Good idea, but I'm a native and many of the sentences are not correct, they are translated literally from English, THIS IS NOT SPANISH. For instance you cannot use "TENER" to express "to have something to drink/eat", you would use "TOMAR", and in this case as well, the translations provided by the comments below such as "¿Me puede dar un vaso de agua?" or "Quiero un vodka y un Redbull" are the correct ones. We translate ideas,not words literally, literal translation does not work. Great idea but it should be perfected by using native speakers as reference.
As the comments say, nobody speaks like in the video, but they will understand that you are a foreigner and charge you more if they can!!:-)
Buena suerte y gracias por el esfuerzo.I haven't watched the other videos but I guess they will be pretty much the same.If you work on it and make sure you stay away from the Spanglish,which is easy to confuse if you grew in a English-speaking country, and use
