How Embarassing!!!!!

Wow did I make a complete ass out of myself. One thing I pride myself on while working is trying to go a little extra to make certain customers feel special. 99% of the time it goes real smooth, but boy did I mess up on that 1% this time. One thing I occasionally do is very carefully open a pack of cigarrettes, slide in a note of encouragement or perhaps a joke or whatever I feel will make a difference in that persons day into the pack, and carefully reseal it to its original form. I have gotten so good at this that you would never be able to look at the pack and see that it was doctored. And I don't even touch the cigarettes themselves. After doing so I hide that pack until the person comes in and give it to them acting as if everything is normal, always a complete surprise to them. Well this time, after doctoring the pack I hid it behind a row of cigarettes the we NEVER sell a pack of, knowing they will never be seen. HUGE MISTAKE. The tobacco rep for the slow cigarettes came in checked all the codes on her products, found that pack of Marlboro lights and put it in front of the Marlboro rack causing them to immediately be sold to a random customer. About a month went by of me wondering who the hell got that pack by mistake. Considering the note was borderline pornographic in nature I prayed it did not get into the wrong hands. The original recipient would have laughed hysterically because of the inside joke, however anyone else would probably not know how to take it.
Yesterday a customer came in handing me a coupon for a free pack of smokes. I informed him I don't take coupons when he told me he got it because Philip Morris sent it to him after he mailed my note and the pack of smokes back to the company. He thought the note was put in their at factory level(which I took as a compliment). He seemed shocked and confused when I told him it was me and the pack was meant for someone else. I now have to wander if Philip Morris is doing a internal investigation or if they just threw the note away. Either way I want to apologize for causing them to give away a free pack because of my mistake. Hopefully I didn't hurt their bottom line.
