Most of the time, a grateful "thank you" is sufficient to get your server/barista/sales clerk through her shift (we know, we've been there!). But occasionally, an extra gesture of kindness is needed. Keep a pack of Little Thank You Notes ($14) from Fifi du Vie (in the second column) in your purse to give out when the service has been above and beyond (no thanks to the grumpy, send-it-back-three-times guy at the table next to you). Just don't use a card in place of a good tip! In fact, add it to your 20% tip and you'll be the favorite customer of the day!
