Wait. Did you mean that you had no fitness from March 2013 to June 2013? Normally, he should be fining you or at least give you some sort of warning. I might be wrong but I know that vehicles which are correctly regulated like here, need the vehicle to be towed to the center for its inspection.
Now, coming to the inspection itself, I usually go there after 1pm or at around 2pm. There's less people and hence no time lost waiting. Everything goes so fast. Once, I reached there at 3pm and one of the guys working there was looking for a lift to port louis. He asked me if I could drop him and he took my papers to make the necessary so that I could get my car inspected immediately :P
Last point: On one of my visits, the officer asked me if "tone ammene l'enveloppe". I did not understand anything and replied him "non".
Later, I understood that he was looking for a bribe (dithé) but my car was in good condition, so he did not bother to explain to me what he wanted exactly lol.
btw, I get lost each time I go there. LOL!
