It's really not too difficult to imagine how this went down. Armstrong, used to being tested by WADA /UCI is put off by the French guy showing up. Responds along the lines of F'U. Takes a bit of time to sort out, before its clear he has to submit to the test.
French guys respond back with "no F'U" by raising this little pissing contest (no pun intended).
Armstrong's known for being less than tactful on occassion, and I'm betting he pissed them off.
