Earlier today, I received a call from someone at Sphatika (New York City) wishing me an early happy birthday. Although my birthday isn't for another couple of weeks, the call was to let me know that I'm eligible for 20 percent off all treatments and products throughout March, my birthday month. It was a welcome surprise, as I don't even remember giving the folks there my birth date. What better way is there to show your clients you care than by remembering their birthdays and then helping them to celebrate. What does your spa do to help them mark the occasion?
