It is pretty common here to see urinal mints placed in sinks. Scent is VERY important here. People carry perfume (guys and dolls) and reapply frequently. Different perfumes go with different occasions, oud (scented charcoal) is burned in small braziers in homes, etc.
Anyway, I don’t find a minty scented bathroom particularly appealing but you get used to it. Today I walked into a small, one person only bathroom that absolutely stunk! See the photo below and guess what they used in their sink?!?
