They provide that service by undercutting Taxis at a loss. I hope you're being sarcastic. Uber is anything by respectful .. and successful I guess in size, but not looking at their bottom line.
I am still waiting for €50 refund for a pre-paid train station taxi booked through SCNF that never arrived. This whole nasty and violent attitude from French can drivers is also unacceptable. During their protests they actually attacked people with rocks and set cars on fire — while still trying to scheme and cheat passengers whenever possible.
