In Russia, never put an empty wine or vodka bottle on the table in front of your Russian hosts or guests. There is a superstition here that putting empty alcohol bottles on the table means poor fortune, which means less food on the table, which in turn means less alcohol on the table. I don't know why, but as soon as I heard that superstition, I immediately started paying attention to keeping empty bottles off of tables. It might be silly to mind or adhere to the superstitions of other cultures...but if the language and metro system work differently, who's to say that karma doesn't also follow different rules in Russia? Anyway, if you don't want to offend Russians, a piece of advice is: "One vodka, two vodka, three vodka, (put the empty bottle on the) floor!"
