One Sunday afternoon, I went shopping at Wal-Mart . But I never thought I would have a life ­changing experience at WalMart.
Although my thoughts were only on speed, the checkout line I was standing in wasn’t moving as quickly as I wanted, and I looked towards the cashier.
There stood a man in his seventies, wearing glasses and a nice smile. I thought, well, he’s an old guy!
For the next few minutes I watched him. He greeted every customer before scanning the items. Sure, his words were the usual, “How’s it going？” But he did something different—he listened to people carefully and then he would reply to what they had said
I thought it was strange. I has grown used to people asking me how I was doing simply out of conversational habit. I could say, “I just found out I have six months to live，” and someone would reply, “Have a great day！”
But that wasn't the end.
He gave them the change, walked around the counter (柜台), and hugged them with his right hand in an act of friendship. He looked at the customers in the eyes. “I want to thank you for shopping here today,” he told them. “You have a great day. Bye-bye.”
The smiling looks on the faces of the customers were priceless. All had been touched by his simple gesture—and in a place they never expected. They would gather their things and walk out, smiling.
Of course, he did the same to me and I got to know his name—Marty.
Who was that guy? It was as if Sam Walton (沃尔玛的创始人)had come back from the dead and invaded this old guy’s body.
I had never walked away from that shop feeling like that.
