I've been here for three weeks now so rus and Alex 444 can give you exacts however I'm an Arab may be I don't look 100% however I don't look Russian and not once did any one give me a bad look or say sth nasty to me. I've seen many Brits here specially near city center and they seem to be doing alright. Knowing Russian makes life easier that's what I came to understand the minute I landed in Moscow. I know very minimum Russian and you could see in the people's face they appreciate the fact you are trying even if you don't make a lot of sense.
Baboshka's or old women do freak me out because just like all old citizen they have an opinion about everything whether it's a garden or how the trolley bus driver drives 
all in all I like it here, and the people might seem distant or unwarm but once you get to talk in Russian you will discover how friendly they are. Yes there are ass holes here just like any country and forget the usual stereotype about Russians it's not entirely true. Yes there are two may be the people I've seen over the course of Two weeks who were drunk at 8 in the morning while in walking to the metro but other than that they are just like us. I actually believe they have nothing against yanks here
