Not sure I should teach that... Well, they stood waiting in the crowd outside the area, and when someone entered the gate, they just moved really quick up behind the paying traveller and in. These gates are open a bit longer to allow travellers with luggage through (and perhaps it also does not close as long as someone is in the way for the gate) so it was quite easy to enter without paying this way.

First time it happened I really even didn't understand what happened, it was just that the offender moved a bit too quickly and a bit too close to the other person to be normal and thus it caught my eye. So I lingered and watched and after a few minutes number 2 did the same, and then I understood what was happening.

I'm not sure it was a group but they were in the same age range, around 30. As someone asked, it looked like americans or europeans but you can't really tell if someone is local or not just by look.

Anyway, I was interested to learn if there has been a change in attitude when it comes to such things, and by the replies here I take it hasn't.
