My good friend her little girl and I did a group hug. It was cute, and funny that next week her daughter insisted we pay with hugs again (so we paid with hugs and money the second time around)
Not necessarily a Lovin' act from McDonald's but DD17 had a bunch of valentines left over from a children's party she helped organize. She was at McDonald's with some friends after the party and asked the manager if he would like the extras to give out to kids who came in yesterday -- they were handmade cards with pencils, bubbles or stickers attached.
The Manager said he couldn't take them since they were a corporate store; but, he comped DDs food and drink to thank her for the offer.
DD and friends took the remaining valentines to a Starbucks and the manager there was happy to share them with their customers.
