Translation:My mother is a waitress at a Chinese restaurant.
Waiter should be acceptable for a woman or man. Waitress is an old fashioned term, especially in US cities
so i put this "my mom is a chinese restaurant waitress" which is the same thing so why
I’ve done that like a hundred times, only got notified about them accepting a single change I submitted.
plus about three slides back the card literally showed a picture of a person and it said "server"
Is there a reason why "My mum is a waitress at THE Chinese restaurant" is incorrect? Is there a distinction between "a Chinese restaurant" and "the Chinese restaurant" in writing or is it just contextual while speaking?
They are different, but the way in which they differ depends on context in both speech and writing. In this sentence "in A Chinese restaurant" means there is no attempt to describe which restaurant, whereas "in THE Chinese restaurant" would only be said where you are referring to a particular restaurant that is already known or specified by the context e.g. in a previous sentence or in the town or place that you were discussing. Without any context you would normally say "in A Chinese restaurant", so I suppose that is why Duo prefers that.
You were right. The problem is that the app does not accept "mom" or "mum" as correct. Which is inconsistent, because the app accepts it as a correct translation for most exercises.
This means poor programming and a lot of unnecessary headaches for users.
It's almost definitely not programing. Programming for natural languages is extremely difficult and even Google Translate still can't get it right.
Instead, they have a database in which non-programmers simply enter acceptable answers one by one. They may try to think of all they can, then they rely on us contributing the rest by using the "suggest" button.
(There may be a tiny bit of programming since I've seen it misapply English contractions several times. Proving that it is indeed hard to do right.)
The course taught '服务员‘ as server, thus the word 'server' should be accepted.
"My mother is a Chinese restaurant waitress." This is another obviously correct sentence that is not recognized as correct in your program.
"My mother is a Chinese restaurant waiter" should be accepted. It's 2018, "waitress" / "actress" / etc are not appropriate words.
Right, "My mother is a waitress at THE Chinese restaurant" marked as incorrect. Really?
