Dammit, a topic that I could have contributed to, if I had gotten to the keyboard sooner.
Anyway, if the mother of the child gave you rusks and ONLY rusks, I'm assuming that it was meant as a snack in which case, I wouldn't sweat it too much that the kid didn't eat. Speaking as a person who has actually tried one of those baby cracker/cookie things, I will say this: I don't blame the kid in the least. They tastes like cardboard.
If you plan on doing this type of babysitting on a regular basis, it may do you some good to do your research into the kid. Ask the mother what the baby likes to eat and buy a couple of jars of that particular food. If you're really in a pinch, unsweetened applesauce or VERY WHIPPED mashed potatoes work well, just make sure the kid doesn't have any allergies. As for the sippee cup, try water next time. Or milk; just ASK before you give a kid milk. Same goes for juice or anything else. If the child is still on formula, it's a good idea to have formula handy.
Every child is different, and you have to learn what the kid likes. Obviously, babies can't talk so it's kind of a giant guessing game to see what will work and what doesn't. It takes parents months to figure their children out and even then it's still an ongoing struggle to learn the kid's behavior.
One other thing to think of is this: Does the child know you? If you're some random strange person that the child doesn't know, then the kid probably spent the entire time with you making strange. Don't take it personally.
