swiss people don`t sleep

kien is tiler. he came to kids of africa today to fix some brocken tiles, some of them in my flat. so we had a talk together and when i told him that i`m from switzerland the conversation turned strange:

kien: do you sleep in switzerland?
joh: ... ? noo, i sleep here, it takes eight hours to switzerland.
k: no, i mean, when you`re in switzerland, do you sleep?
j: in general?
k: yes!
j: ... yes, of course. why?
k: once, somebody told me that people in switzerland don`t sleep, they work always. isn`t that true?
j: no! i mean, we work a lot, i used to work ten hours a day, but afterwards, you need to sleep!
