Le petit-dejeuner is French for breakfast. The French eat breakfast quite early in the morning, soon after the sun has risen. Typically, they have a light breakfast with a hot drink. There's usually no cooking involved.
In the northern provinces/ the Randstad you'll get "Go away coffee". You will be offered coffee and then are expected to leave. In Limburg you are expected to stick around and have a bit of quality time with the host.
