A couple of mornings per week I stop at a local McDonalds for coffee (yes, I am very bad). There is a young man with an amazingly sweet smile who works at the drive-thru window. Usually he is the one who hands me my drink, always with this big smile as he wishes me a good day.
Today he was at the first window, where I pay for my coffee, and he took a moment to not only wish me a good day, but to thank me for my consistently courteous interaction, because I typically smile, bid him good day in return, and say thank you when he hands me my drink. Apparently not all customers are friendly or even polite. I respond to him because this young man is working at McDonalds and from my place on the other side of the counter he is putting forth a concerted effort to do a great job. From our few seconds of interaction once, maybe twice a week, I have a extra positive start to the days, because a cheerful young man working aminimum wage job smiles genuinely and sounds sincere when he wishes me a good day.
Thinking about it now, I still smile. What he shares so freely is refreshing and priceless to me.
