That doesn't apply to the people at the shop.

It's in the best interest of the shop to stop this kind of thing ASAP so they're far more likely to call the cops if there's an altercation at their door that's even going into the shop.

Further, it also depends on the kind of country.

I lived in the UK: it's far more violent as societies go and far more prone to "I don't want to get involved" behaviours than other countries in Europe. I've seen the way people respond to the same situation in for example England and The Netherlands and it's very different.

Don't assume that what you see in Manchester is representative of what you would see in Paris, and definitelly not of what you would seen in Northern Europe.
