Several studies have shown that people eat faster and leave sooner when loud music is playing -- so restaurants have been turning up the volume to increase flow-through.
And this isn't the only tactic restaurants use. Diners seated at tables in the middle of the room tend to be less comfortable and eat faster. The same holds true for uncomfortable chairs.
They also want you to eat more as well as faster. Warm colors -- like red, orange and yellow -- stimulate the need to eat.
CNN reports that:
“On hectic nights, the reservationist at Salumeria Rosi Parmacotto in New York City will inform diners that they need the table back in 90 minutes for the next party.If you lurk over your digestif too long, chef Cesare Casella will place your name on Salumeria's ‘no salami’ list.”
