My most recent is very similar to an above story... Today I went to CVS to fill a persciption for my husband. I had a $25 coupon for a free gift card when filling a new scrip.
I also got another coupon, in store last week for the same.

There had been a man in front of me in line with a new perscription, he smiled at me. Isnt it crazy how a simple smile can make your day?

anyway, my scrip came up first. Once i was done I went to find him and said, "this is totally random, dont think Im wierd LOL. but here is a coupon for a $25 gift card, please use this when you pay for your meds, you will get a $25 gift card as i just did!" He said thank you SOOO Much. this is truly my lucky day. I said sometime in life, remember to pay it forward!

I love to make people smile, and he smiled w/o being offered anything in return so I felt like I was already paying it forward by sharing.
