Apparently the title above is a policy for at least one store clerk in a Swiss store. And when your customer is Oprah Winfrey, things probably won’t work out too well.
I’m wondering where such European bigotry comes from. There are a number of possible sources, but African-Americans until fairly recently described attitudes in at least some European countries a quite tolerant, though there seemed to be a fair amount of racism in the UK in the 60’s . I would guess, then, that the racism in Switzerland is due to immigration.
If that is so, then we probably won’t find implicit biases, race schemata, etc. The demands of being PC may have had a good effect in the states.
