My kitchen sink had a drain issue, the plumbers we know were busy so I called another one and he came quickly.

The whole process took around 30~40 min, and in the end the plumber said the price is 776Fr, which surprised me. I'd done this before and the price is usually between 150~250Fr, and sometimes it took longer (e.g. 90~120min) than this time.

What's the regular price of unclogging a kitchen sink in Switzerland?
