The moral: do not walk arount with a thermos, not at this day and age. I remember 8 years back episode when my husband went to the Ministry of Transportation for some paperwork with a briefcase that had numbered locks on top. He did what he came for and left, but forgot this thing under the table. In 20 minutes he remembered, went back and found building buzzing with people running out,police everywhere, yellow tape. They thought there is a bomb in this briefcase and demanded evacuation from the building... Say thanks to Osamalike, they started paranoia.
I was on the Moscow subway (Metro, they call it) with my Russian girlfriend, now my wife, just a few months before 9/11. People came and went at each stop, and we found ourselves at the back of the car, alone except for an unattended package in brown paper. We got off at the next stop, at my girlfriends insistence. Not that I needed persuading. She alerted an attendant who called (I assume) to security at the next stop.
Never heard anything more about it. Probably nothing. But other countries have been dealing with terrorism for a lot longer than we have, and the citizens are attuned, though not panicked by it.
