Often, a problem I encounter is that in rainy seasons the rains come really suddenly. It is really difficult to find stores or pedestrians who are kind enough to lend an umbrella to a stranger (in this case, the poor stranger is me), and I end up getting stuck under a random canopy waiting for the rain to stop.

What can I do to get home quickly (or make progress doing so) without an umbrella and avoiding getting wet when I'm stuck in the rain?
