It's my understanding the interpreter was requested. I don't think that's the message being sent here. The message would be more like "we comply with this reasonable and lawful request because it makes you, our valued employee of 6 years, even better at their job".
And you're not getting one employee for the price of two, you're getting one employee and a one assistant. Executives get assistants all the time and no one blinks an eye. What, are they so incapable of scheduling their days themselves?
