A customer shot a waiter dead at an eatery on the outskirts of Paris, apparently enraged at being made to wait for a sandwich, according to a source close to the investigation.
The waiter's colleagues called police after he was shot in the shoulder with a handgun in the Noisy-le-Grand suburb east of Paris on Friday night, the source told AFP.
Attempts to revive the 28-year-old failed and he died at the scene.
The gunman, who a witness said lost his temper "as his sandwich wasn't prepared quickly enough", fled the scene.
Police told AFP a murder investigation has been opened.
Local residents said there are high crime levels in the area, notably drug-dealing and public drunkenness.
