Swiss German uses a lot of French words, so a delivery driver is called a “Chauffeur”. This word used to mean “heater” too.
There’s a sign on the door to the delivery bay of the local supermarket saying “Chauffeur – bitte Ware in den Kühlraum mitnehmen”. Which actually means “Driver – please take your goods into the cool room”.
But which could also mean “Heater – please take your goods into the cool room”.
Which doesn’t sound like a good idea…
