When you are one of the few Europeans in a small Kenyan town, you get notices. Conversely, as a Stargardtien, I often only notice a different skin colour in hindsight.
The colour of the plate helps to see what is edible on it (see the article “What am I eating there?”). In Kenya, I had to revise my preference for white plates. And since some dishes are eaten with the fingers, new challenges emerged for a Stargardtien.
The street vendors are sometimes a bit pushy, especially when they appear in bulk, such as around a Matatu station. As a Stargardtien, I have a built-in “deterrent”.
It is not always easy for Stargardtiens to recognize what a market woman or a shop offers. And the name of the shop doesn't sometimes help either.
If one's own currency is sometimes not clearly distinguishable, how will it be with an unfamiliar one? The current Kenyan bills series has been in circulation for quite a long time and you can see that: they are very hard to distinguish.
