Finally,I got a part – time job working at the local coffee shop.I had figured that the job would be easy.However,the actual situation was not what I had expected.The customers were hard to please.There was always too much sugar,too little ice,or not enough skimmed milk.However,I kept at it.
One rainy day,Hank,one of my regular customers,came in looking sad and defeated.I asked what the problem was sand if we could help,but Hank wouldn’t tell me any details.He just said he felt like going to bed,pulling the sheets up over his head,and staying there for a few years.I knew exactly how he felt.
Before he left,I handed him a bag of his favorite type of doughnuts along with his iced coffee.He looked at me skeptically because he hadn’t ordered anything else except iced coffee.
“It’s on me,” I told him.“Have a nice day.”
He smiled and thanked me before turning around and heading back out into the rain.
The next day was a horrible one.The rain kept pouring down and I spent my afternoon hanging out the window,handing people their orders.What’s worse,no one felt like tipping that day.
However,around 7:00 pm,Hank drove up to the window.Instead of ordering anything,he handed me a single pink rose and a little note.He said that few people take the time to care about others nowadays and he was glad there we still people like me in the world.I was speechless and very touched; I hadn’t thought that I had done anything incredible.
