Only in Russia. Or is it? I walked into TSUM, a very fancy mall full of boutiques, kind of like Saks Fifth Avenue. And there were no restroom signs anywhere. I decided to investigate and asked where a restroom is. The sales person reluctantly told me it's on the 5th floor. So I rode to the 5th floor, and there in front of a very fancy door sits a woman in a fancy suit with a fancy hairdo. She sees me, gets up, and with a practiced smile (the kind that looks more like a rictus) says, "100 rubles for the restroom." I balked. I paid 30 rubles at the train station (it's typical to pay for a restroom, with a lady sitting there by the entrance and doling out toilet paper), but this was a bit much. It was so ridiculous, I laughed. I suppose wealthy Muscovites don't have to pee, or if they do and they happen to find the restroom (only one way up on the 5th floor, and no signs), 100 rubles is really nothing to them.
