French fries machine

Seb spotted this french fries vending machine while we made a stop at the gas station along the autoroute. We were really tempted to see how "just made" were the fries. But no one was using it since there was a canteen just behind this thing.

And no, we were not desperate enough to try it and wasted our money in case . . . . . we did not like it. So, it is still a mystery to me whether the fries were pre-fried and heated by mircowave upon purchase; or were they really fried in oil in this machine. Is this hygienics?

Someone, just someone, go try it and let me know. Okay?
