Entitled: "Ten minutes for refreshments." A rush hour or peak hour is a part of the day during which traffic congestion on roads and crowding on public transport is at its highest. Normally, this happens twice every weekday, once in the morning and once in the evening, the times during when the most people commute. The term is often used for a period of peak congestion that may last for more than one hour. Published by Great Atlantic & Pacific Tea Company, 1886.
