Would You Take £1 From A Stranger?

Pound Coins
When I think of projects like this, it is then that I bemoan the loss of the one pound note. Anyway...

I saw this article on Huffington Post Parents this week.  Basically a lovely retired couple occasionally take to the streets and offer random acts of kindness. This time they are offering one dollar to drivers at a crossroads in their home town (and check out the video further down that article - it makes me want to head to a roller disco right now). 

So the question is, if someone offered you a pound, would you take it?

What if it was offered by a known and respected member of the community?
What if it was offered by a teenager wearing low-slung jeans, trainers and a hoodie?
What if it was offered by me?

Are we automatically suspicious and want to know what the catch is?  Do you get 'something for nothing' in this day and age?  Because you don't need that pound, does it make it immoral to accept it?

If you accepted the pound, what would you do with it?
