Food for the junkie. I think these things are typical Dutch (at least the "kroket" and the "frikandel"). In those small warm boxes they are waiting for you...snacks!
You can change your money at the mechanical pimp on the left. Put the money in the slot near the box of your choice, open the box and the "food" is yours!
How long your food was in the box?.....nobody knows....
Do you have this in your country?
Holland-Nijmegen, snackhouse "de Blauwe Steen" corner Burchtstraat/Broerstraat
Btw, this snackhouse is a good and clean one!
