I'm running a folk concert in a venue in which the bar is in the room. Some of the audience may not be familiar with folk club etiquette (as I see it) so a notice will go on the door asking people to respect the performers and only to enter and leave between songs.
However, at a previous event it was the BAR STAFF who were too noisy. I'm trying to think of a little notice to leave on the bar to quieten down the noise from bar transactions and idle chatter behind the bar. So far I've come up with "KINDLY SHUT UP - THE AUDIENCE DIDN'T PAY TO LISTEN TO YOU!".
Can anyone think of a witty and polite way of asking people to be quieter?
