Using a thank you in business is more than just those two words.
From the time I was in seventh grade until I graduated Glendale High, every summer I toured with my church's youth choir.
To make it financially feasible, we stayed in host families' homes for the night before we went off to our next destination.
On my first trip, about to find out whether I'd hit the jackpot with the hosts who had a pool, or gone bust and have to share a pullout couch with someone, I stepped off the bus.
Our youth minister pulled me aside, "Did you pick up your host gift yet?" I sheepishly answered, "No."
He replied, "That's OK, you're new. Here it is - a wrapped set of note cards and here is a card and envelope. Fill out the card and thank them for hosting you tonight. Add one specific thing about their house, their hospitality, or even a good breakfast. You can either give it to them when you leave their house or leave it on the bed but don't forget to do it."
I asked, "Do they really care about a notecard?" He laughed and said, "No, they don't. But everyone wants to be noticed and appreciated when they have done something you benefited by."
That youth minister knew the power of making the effort to show gratitude and say thanks. He even gave me the word for thanking customers or customer appreciation: for.
Here's a partial list of who to thank to get you started:
You get the idea...
"Thankfulness is the beginning of gratitude. Gratitude is the completion of thankfulness. Thankfulness may consist merely in words. Gratitude is shown in acts." - Henri Frederic Amiel

It usually starts, "Thank you for...."
Retailers can make the world a more civil and hospitable place through a lot of customer service efforts, this is just one.
