Hyaku…love the name - domo arigato….In the Middle East when I worked there for too many years….I found the locals cutting in front of me pretty regular….so as I was much taller and bigger than them… I would just stand on their feet till they backed off…grind it in till they got the message....wearing their sandals…and getting the pain….they'd step back….Worked a charm. Wear heavy shoes and try it there…..
