LAGNIAPPE, and other things

Loosely defined as "something given or obtained gratuitously or by way of good measure", the concept of lagniappe or la napa is Spanish in origin, later adopted by the Creole French.
If you are fortunate enough to be as old as I am, you might remember this concept played out as the baker's dozen: you bought a dozen donuts, and the baker might throw in a 13th donut, just because. Or so you would think. In reality, the practice dates back to medieval times, when bakers would be flogged if they cheated their customers by providing anything less than that for which they had paid. To be extra sure that they didn't miscount, bakers began throwing in an extra loaf, as a precaution against a possible flogging.
Thank goodness, it's not the fear of a flogging that makes us want to include a little something when our customers keep returning to purchase our baked goods. In some cases, we just want you to try a new cookie we may have baked. In others, we know that you may have ordered a dozen cookies, but the temptation to have one 'on the way home' is just too much to resist, and you can't show up with one less cookie for your family (don't worry, Beth, I won't tell anyone).
So, we are bringing back the baker's dozen. Anytime you order a dozen of our cookies, or bonbons, or whoopie pies, we will throw in one on us. Just because we're nice like that. But we are not too nice either - in order to get your lagniappe, we invite you to join our newly minted Baker's Dozen Club. Simply sign up, and every time you order a dozen baked goods from us, you will get one on the house. Bonus, you will also be the first to know about our new products and promotions. 
This has really inspired me to think of more old-fashioned customs or traditions we can bring back - any ideas? I'd love to hear your thoughts, and if we like your suggestion and implement it, we'll send you a little something. Now, isn't that nice? 
Also, just a little reminder: with a graduation, family visiting, birthdays, and a trip coming up, we will not be at the Midtown Farmer's Market until July 14th. Except for when I'm traveling between July 3rd through the 11th, our ovens are still on, baking up cookie gifts for teachers, graduation cakes aplenty, and decadent pies. 
Now, please excuse me while I go cry my eyes out so I don't embarrass my daughter during her Senior Assembly tomorrow, at which she is one of the speakers. Wish me luck!
