You know what would be a brilliant marketing scheme for an umbrella company? Or even just an idea for a business - Umbrellas to your Doorstep.
I don't have an umbrella and it's pouring rain right now. I would pay a pretty penny for an umbrella to be delivered to my office. Seriously, does anyone want to start this business? It would clearly be great in a place where it doesn't rain too often and people aren't prepared for rain. Or a city full of Nomadic Gnomes who are too cheap to buy umbrellas and only realize the importance of them when they have to ruin their beautiful shiny hair in an unending thunderstorm.
