How to know if the oil in a car has really been changed?

I took my ten-year-old car to have the oil changed last week. Today it wouldn't start, so it was towed to a different garage; the mechanic says it needs a new alternator and battery and an oil change, as the engine oil is black. So--is the only possibility that one of these garages is lying? And for the future, how can I tell if the oil has really been changed or not? FWIW, the guy today was setting my Spidey-sense off--he was really pushing me to buy the more expensive battery and alternator and in general was very aggressive, while the other guys I've used before and they don't set off any alarm bells.
