I myself have had my run ins with them, while walking into MacDonald's earlier to once again use the free wifi I had one actually push me out of the way to get in, then the same one elbowed me out of the way to get to the counter, then once she had received her order she turned straight round and knocked into me spilling her drink, she then went bloody mental at me in Russian some of which I understood. I started with 'devushka' and I think the words 'f*ck' and 'b*tch' were in there somewhere too, having yelled at me she proceeded to hit me pretty hard for someone who looked about 90 and then stalked off. I was in shock for some minutes because behaviour like this simply doesn't happen in the UK. The older generation are usually so scared by the 'Youth of today' that they normally avoid them like the plague. While I would like to see this situation change and have the pensioners not live in fear I most certainly do NOT want them to be as bloody rude and heartless as they are here.
I think the best thing to say is stay away from stray dogs and babushku!
