It’s the annual Starbucks Christmas Open House.
Starbucks will be giving out free coffee on 6 Dec 2007 (Thursday) between 5pm to 7pm. You can make a donation of any amount and all proceeding will go to The Salvation Army. BTW: This only applies for Singapore Starbucks. Not sure if other countries have similar events too.
Expect long queues. For me, I’ll rather go on normal days so that I can enjoy my coffee peacefully.
