Bruce was Secretary of life at Obama, the White House. One day in March 2012, he was ordered to come to a famous Buckingham Palace near England.

I want to buy a pair of leather shoes for president Obama.

John Rob, a shopkeeper, warmly received Bruce.

According to the confidentiality requirements of the White House, Bruce could not tell rob his true identity, let alone pick up shoes for Obama.

"Welcome to rob shoe store. What style do you prefer?

"Asked rob.

"Oh, yes, in fact, I bought shoes for a friend. Show me the best leather shoes, please.

By the way, he wears 43 yards.

Bruce replied.

"I'm sorry, but in that case, I can't sell shoes for you."

Rob shrugged.

"Why? I've told you his shoe size. What's the difference between his coming or not?" Bruce was puzzled.

"Because we have to be responsible for the sale of each pair of shoes that are really fit for the feet of the customers."

"It doesn't matter. If it really doesn't fit, I will not blame you. You dare to help me."

It is your business not to blame, but it is our business not to sell any pair of shoes that are not fit.

If there is nothing else, then I can only excuse myself.

Rob continued.

Bruce was finally enraged. He shouted to rob, "do you know who I'm buying for shoes? Barack Hussein."

-- the current president of United States of America! How can he have time to come here to try shoes?

Bruce thought that Rob's attitude would immediately come to a one hundred and eighty degree turn, but he did not expect rob to reply lightly. "The people who come here to buy shoes have only one name and identity. That is Rob's customers. Please, Mr. President, you have to measure feet and try shoes. There is no other way!"

After a little calm, Bruce conceded again, or else, you sold me 39-44 yards of the same leather shoes, of course the quality must be the best ones, so that there was always a yard for the president.

"Rob's shoe shop has 150 years of history today, and I will not destroy this rule from my ancestors."

Faced with the shopkeeper who had no food for the past, Bruce had no other way to go.

But before he left, he obtained a privilege -- free to visit the storeroom of this shoe store, where Bruce saw many wooden pin models left behind by feet, including Churchill, Conan Doyle, Charlie Chaplin, Anthony Hop-Kins and so on.

At this point, Bruce really understood why this shoe store was so popular with many big shots.

For every pair of feet, the secret of a hundred years shoe store's success is so simple.
