Nice jokes and punnage… I don’t want to ruin that with some facts:
My Swiss friends are very much normal people, factory/office workers. I’m sure their salary will be ok compared to UK average, but everything in Switzerland costs so much that they’re disposable income is stw average I guess. They have an apartment in a block with underground car park. One of the bays is a dedicated washdown bay for cleaning outdoor gear. They say it’s quite a common feature, more so on slightly older buildings. Because they wash the bikes fresh before they go in the lift to the apartment they probably don’t need detergent, but I think I recall that we did use something like muck-off.
