Hablar con el camarero

[fallingdog]

I have this exercise I am doing in Duolingo that I don't understand.

The solution is:
?Tu hablas con tus papas en espanol? Entonces, !habla con el camarero en espanol!

I had this and got it wrong:
?Tu hablas con tus papas en espanol? Entonces, !hablas con el camarero en espanol!

Google translate gets me this for the correct solution:
Do you speak to your parents in Spanish? So, talk to the waiter in Spanish!

Why is the second hablar with the camarero not hablas? Maybe if I said hablas con camarero it would mean, "you are talking to the waiter in spanish... like a statement of fact not a order... Is that the problem?
