I was on my ordinary way to muai thai club, when I bumped into some sort of an incident today. A central station (Gostiniy Dvor), a dozen of people trying to enter a train car that is about to leave, I`m trying to make my way through, when one petty man, ca. 40-45 y.o., grey hair, in suit and probably not of russian origin holding a flower is pretending that he is trying to get out from train, in reality he`s just blocking the way for everyone, some mess is starting out, then in 5-10 seconds when I finally got in it came obvious that a pickpocket just tryed to steal a wallet from a nice german couple. As one russian was still trying to hold the door, hesitating if to follow the "thief" or not, asking (in russian) them if they`ve lost something, those replied with shrugging, and nothing better came into my mind to say "Do you miss something?".
I realized pretty soon that it sounded kinda weird, though they got the point and assured me that (hopefully) it`s ok.
And I still bugging myself for freezing like that, not the first occasion when my fluent english turns into sht. under stressful situation.
What was the better way to ask? "Are you missing smth?" or anything different?
