Translation:I am sorry, but both of these tables are reserved.
Should probably accept "I am sorry, but both these tables are reserved." (without the "of")
Tato byla bajecna lekce, ale je chyba! When I got to the last question it asked to translate "I reserved a table for seven o'clock". I put this in, but it was wrong 3 times in a row. I turned off the audio with the button and it showed that the question was actually different.
