Sounds unlikely to be rocks. Probably either chipped by putting on or taking off wheel balancing weights, or when removing or refitting tires with the machine, assuming the operator was doing it wrong. As you said I can;t imagine rock chips happening suddenly when you've never had any like this before and coincidentally at the same time, on two tires at once, on the lip on both, and just so happens to be the two they worked on for you. It may very well be true that their machines didn't do the work, but maybe somebody there dropped something on the wheels, curbed them while driving the car, etc.
If you tell them you know your car inside and out (of course) and you know the condition of the wheels before bringing them in, then they have no real argument. They get discounts on wheel repairs and could have them fixed for you. If the manager won't help, go over his head to corporate, especially if it's a chain. As soon as the person you're dealing with stops helping you, it's always best to move on to their superior so you don't keep wasting your time. By the way, I've been told by two friends who are managers at different stores that whenever a customer says "this is wasting my time" they are instructed to assist them if at all possible because they can't readily compensate for loss of work, days off, etc. Weird but seems to work.
