Umbrella Rentals

So often, working in the big city, you get all way down to the lobby only to find it is raining outside. You were only popping out for lunch, so you didn't bring your coat, and while there may be itinerants standing around selling umbrellas for $5 a pop, you already have quite a collection back upstairs and it's just too much effort to go back upstairs and retrieve one. So rather than buy one more, you just brave the rain and dash across the road for lunch.

So, for these enterprising itinerants, I propose a new service: umbrella rentals. The umbrellas would still cost $5, but now they would accept returns at, say, $4 apiece. Save us all a soaking without creating further umbrella stockpiles.

[Sorry if this does not make much sense to people who don't work in skyscrapers, or have a flock of umbrella salespeople appear at the first drop of rain.]
