If you're American, you better keep double the distance.

To be fair, Americans are twice the size compared to normal people.

What about with any other non-italian speaker Europeans?

use metric system

1 italian meter = 6 american feet

I have big feet, so i need to be further away?

Because of their fatness

Don't say it! Don't say it! Don't say it! Don't say it! Don't say it! Don't say it! Don't say it! Don't say it! Don't say it! Don't say it! Ahhhhh BECAUSE THEY'RE FAT!!!!

Metric peasants are too stupid to understand imperial master race units :)

What's the problem?

Because europeans have terrible BO.
