Yeah, I've had offers rejected, and then they raise the price to what you asked for. Many of us have found that once you get a price for a specific location, you can request it again and you will generally get it. It doesn't seem to be working quite that way with their fast casual client at the moment, although I did get $2 extra for one location last week.
Also, others have reported getting rejected for even a dollar more than the offer price, which makes you wonder why they even allow you to make an offer if they're never going to accept it.
