Good Service - Starbucks Siglap (Update)

A couple of weekends ago, I posted about the good service I had received at a Starbucks outlet in Siglap. At the same time, I had written in to Starbucks, 'cos I thought that the lady's bosses ought to know what a valuable employee they had. A few days later, I received a thank you email from Starbucks in which they also asked for my address. And today, I received a thank you letter from Starbucks with a couple of complimentary beverage coupons enclosed. How's that for good service?
