Yes, I had a terrible au pair who thought she was entitled to a brand new iPhone. Also, she couldn't be bothered to answer the Android phone I bought for her (even though I explained to her that it was her WORK phone, and that's why I paid for it). But she sure would have raised holy hell if I *stopped* paying for the Android phone she didn't use (she was always texting on her iPhone she brought from home).
This is why I no longer have an au pair. Too many girls sign up for a free American vacation with expectations of a luxury phone and car, then are *shocked* when they are expected to do work, and not given a more expensive phone than the one I have! It's just ridiculous.
