Помогите сделать качественный перевод:

One Friday lunchtime I had to change some money and went to an exchange office on the main pedestrianised street in the city.
There was a queue of about half a dozen people also waiting to change their dollars. Now queuing is something that the English do when they have to but we tend to think how to avoid the queue - usually find another place or later time.
This time I was saved by a young man who suggested that if I wanted to change a few dollars we could do it quicker outside in the street.
I followed him outside and gave him the two $50 notes. While I was waiting for the money I was tapped on the shoulder by another young man who explained to me that it was a slightly dangerous practice to change money on the street.
I was embarrassed by this warning, and now wantend to get out of this situation as soon as possible. I turned to the chap and he returned the money immediately and went down the street. I stuffed the money in my pocket and went in the other direction to find another place to change my cash, But when I took the two notes out of my pocket i saw two one dollar notes! I might have saved ten minutes but I had lost nearly $100 instead and all because of my own stupid greed and impatience.
I was still wondering where to seek help when I saw the two chaps who had taken my dollars. I came up up to them and asked if they wanted me to explain the story to the militiaman who was a few metres away. They quickly handed me the two $50 notes - which this time I checked before pocketing them.
I was so glad to have my greed rewarded with some great luck that I gave them back theIr two one dollar notes - so they could catch someone else out? I don't know why!
