When (ex) President Hollande took his first holiday excursion to the South of France, the man of the people forsook the Presidential jet, and took the TGV instead. This humble act of travelling as ordinary folks do actually caused chaos and cost millions. By law, every bridge, crossing and tunnel had to be protected by police, and thousands of them were diverted from ordinary duties.
When he finally arrived, his jet was waiting for him at Toulon, having flown down empty.
