I don't think that it has anything to do with honor. If there is a good way to get yourself killed in SA, it's probably messing with SA Rugby honors. They do not take that as a joke.
I can't believe I've looked at this burgeoning list and no one has mentioned wine or fine cheeses (I like to buy the imported goat and sheep ones myself).
We also regularly buy organically-raised/grown veggies and fruits, the big boxes of Sunkist oranges when they have them, and the wild-caught fish, of various types. When they have them. And the sardines. :)
Finally, I got my second Shringrix vaccination at a Costco pharmacy.
