The first London Olympics 2012 tourists
These are some of the first 'tourists' who have arrived in London for the 2012 olympics:
And as one can ascertain from the typical road scene once a bus drops a dozen of them in a western city, they behave quite frequently (up to the moment, all the time so, but maybe somebody can make them improve their behavior using time-proven Singaporean methods) like this:
And there's still 70-odd days to go until the Olympics start so the buses from eastern Europe will be able to make many more trips to fetch more of these folks that we also have to remove from their camps in Geneva and some other places.
There are simple ways to get rid of them - transport them back, without any money given, and if they start begging, don't give them a single cent and make them go to sleep hungry. Once they find out life's better in their place of origina, they will stay here.
