Finding a free "turn off your mobile" sound clip
Does anyone know where I can find a free sound clip of someone saying "turn off your mobile/cell phone" for a small theatre.
It must be:
a) Verbal (since it will be played over speakers)
b) Suitable for a theatre (i.e. no swearing, easy to hear).
d) Downloadable (or on a site like YT)
Any links would be much appreciated. All the clips I can find on YT and elsewhere are designed for movies and therefore visual in nature.
