Boy does this drink go horribly WRONG.
A lot of bartenders like to offer some kind of spectacular signature drink that sets them apart.
In Siberia, there is a bartender who lights a drink on fire and gives it to guests. He usually he uses Sambuca and hasn't had problems .. well a recent customer wanted him to use absinthe instead.
The bartender did it, but only after a warning. The customer should have heeded the warning as he caught on fire. But of course NOW the guy is suing the bartender for $15K.
