Bobby continued, “She told us that soon everyone will have a Berry Price Meter that tells us what the Berry price is every minute. The Berry Factory will send out the price like a text message on your cell phone. She thought most people would put the Price Meter on the refrigerator door where everyone can see it, because almost everyone in every house likes to be in the kitchen. The Price Meter will also say what the Berry price will be at night, and on weekends, so we can decide whether we really need to have the Zervs work for us right then, or whether we can have the work done when the Berries are less expensive. She said that there will be two periods during the day: an expensive time and an inexpensive time. She called the expensive time the “peak” period, which might be between 1 in the afternoon and 6 o’clock at night, and the inexpensive time she called “off-peak” that would be any other time of day or night.”
