How to survive Cannes Film Festival

Below is the Cannes Film Festival survival guide from an early 90's t-shirt.

Never go out without dark glasses
(Even if nobody would know you)
Never be without your cellular phone
(Even if it doesn't work)
Never take off your official badge
(Even at night, one never knows...)
Never look lost
(Even if you can't find your hotel)
Never go out without visiting cards
(Even false if you are not a producer)
Always look busy
(Even if you've nothing to do for hours)
Always smile at the photographers
(Even those from minor papers
Always have lots of files under your arm
(Even if they only contain advertising brochures)
Always go to the "'in" places
(Even if you can't stand the noise and the smoke)
Always know at least one producer
(Even if he doesn't know you)
GOOD LUCK AND HAVE A FGOOD TIME
