Next Thursday, March 15th, plan on stopping by your local Starbucks between 10am and 12 noon. During that time, Starbucks will be holding is 2nd annual Coffee Break. All company-operated and licensed Starbucks stores in the U.S., Canada, New Zealand, Australia, Thailand, Malaysia, Indonesia and Greater China will be giving away free Tall (12-ounce) cups of coffee to anyone who drops by. Starbucks Coffee Masters clad in black aprons will be present during each of the coffee breaks to kick off the company's spring brewing sale and to answer any questions you might have about the coffee or coffee brewing. Last year, many stores used the coffee break period to sample some of their pastries out to customers waiting in line, as well.
For the location of the nearest Starbucks, you can look at their website or text your zip code to "MYSBUX" (697289) for a return of the three nearest stores.
Update: Apparently, the Starbucks stores outside of the US and Canada will not necessarily be participating on March 15th; some will be hosting their coffee breaks on different days. You might want to check before heading over!
