It's a good strategy and works indoors too. For example, I know a bunch of financial auditors who basically go into businesses and annoy the shit out of them for a few weeks making sure there's no fraud going on. They say it's extremely common for them to get stuck in uncomfortable spare offices, it'll be small and cramped, too hot or too cold, they work late into nights and weekends and the client will intentionally make sure ac isn't on late, things like that. Also works at home for getting rid of company that overstayed their welcome.
