When this happened, did he give you an exit stamp?
One time entering Zurich, the immigration agent flipped through my passport, then complained he couldn't find the entry stamp for my last trip (< 3 weeks prior). I offered to help him find it, but on mentioning that I entered in Madrid, he lost interest, stamped it and let me through. So they do occasionally check stamps, but my impression is that without another reason to be suspicious, mentioning entry/exit through one of the, ah, less diligent EU ports results in quick passage (and perhaps a rant, as someone mentioned)
Thankfully those less diligent ports have always stamped me so far, so I have a 1:1 entry/exit stamp ratio, but if I didn't and were concerned, I'd imagine bringing some kind of evidence of entering/leaving on a certain date would be sufficient (maybe, e.g., ticket stubs, old itinerary)
Non-RFID passport, FWIW
