Doesn't matter where they come from. Slam the Thai law at them! Being drunk is no excuse; set an example and get rid of this kind of tourist!
Italians named Ian Gerstgrasser and Tobias Gamper ... 555 Who would believe that? I think Jan Gerstgrasser and Tobias Gamper which are typical German names might be correct.
Ian your geographic knowledge about Europe or Italy stops probably in Kamala! There are a lot of German named Italians in Northern Italy. The region of the Alps is called Tyrol! It's even a German-speaking region as 2nd language and the Tyrolians are proud of it.
It's no rocket science to know how sensitive some countries react when it comes to their flag. Otherwise send them back to school and punish them for stupidity. Hefty fine and deportation and a new learned lesson for these spoiled brats. Thanks.
Kamala Ian, The former Austrian South Tirol is part of Italy since Austria as a German ally lost WW1. You heard about Versailles 1919? They speak German there and feel more Austrian than Italian. Maybe they come from there.
Ignore their pathetic sobered-up statement and punish them hard. 500 baht should do it.
Give them a free reservations for several months at a Bangkok hotel - perhaps the Hilton - and let them meet some of those nice prisoners there. They deserve it!
You are perhaps speaking of their ethnicity. Their legal status, per their passports, is Italian. The world is changing, no?
