The US Irish pubs often go out of their way to seem old-world, e.g. sawdust on the floor, not something I see a lot in Ireland..

> sawdust on the floor

By covering with sawdust to absorb excess moisture before sweeping it up with a broom and dustpan is most usually how vomit is cleaned up by employees.

I mean the entire floor, in the middle of the day (no-one vomiting).
