The staff at our overpriced hotel in Moscow were definitely not required to smile at their customers. We ordered two cappuccinos at breakfast time but the waitress seemed offended. She scoffed, did a dramatic eye roll and tsked as she walked away. I would see the same behavior at the infinite number of metro stations, restaurants, museums, and parks.
Although I'm not a chatty social butterfly, Russians stroked me as a tad distant, a tad un-engageable, a tad impenetrable. I'm still wondering if decades of a communist regime altered not only the collective but also the individual characters of Russians. Or maybe, it's just Moscow. Maybe Moscovites are to Russians like New Yorkers are said to be to the rest of America.
