“Flambéur” isn’t right but “flambeur” means something else entirely (gambler). “Flambéer” would be more legitimate but would be hard to decipher. The title tag plays it safe and uses “flambé restaurant server”.

[gregschlom]

"flambeur" means someone who sets things on fire. Either literally, as in this case, or metaphorically, as in money.

[Lalabadie]

Flambeur with this meaning is a metaphor (it can mean gambler, or just overspender).

Its literal meaning as "quelqu'un qui flambe" remains correct too.

[tomjakubowski]

like somebody who "burns through money"
