Thought I was going to end up spending the night in the cells. Me and a coupla mates had gone into town to get some chips at about midnight. Came across a guy whose car wouldn't start so were trying to push start it. Transit full of CRS pulled up, one wandered off onto some waste ground for a p!ss, others demanded to see the car guy's papers for him and the car and two others demanded to see all of ours. I stupidly had left my passport at home so decided to act dumb and incapable of speaking French, having told my mates to explain I was a thick bloke who came to visit them. (I was in fact living and working there). and that I didn't know the law. They managed to calm the guy down and, once they showed their passports and vouched for me, we were all allowed to go on. But the CRS were renowned for being thugs, many from Brittany and places of high unemployment.
I made sure I had my passport on me from then on! Twas a bit of a bricksh!tting moment, for sure!
