Bestow random acts of kindness, and you may be rewarded in unexpected ways. No, we’re not recalling a message from our last fortune cookie, but the latest holiday promotion from Macy’s.

On Friday, Dec. 11, two street teams (dubbed the Macy’s Believe Newsboys) will be roving through downtown San Francisco looking for people doing good acts in their daily lives. When they spot a deserving individual, street teams will reward them for their positive deeds and acts of kindness with $25 Macy’s Believe Bonus cards, good toward future purchases at the department store.

The promotion is part of Macy’s National Believe Day, which encourages the spirit of the season through various charitable initiatives.

Want to increase your chances of crossing paths with the street teams? We hear team one will be trekking from Union Square to Macy’s, the cable car turnaround at Powell and the Civic Center Bart, in that order, between 10 a.m. and 2 p.m. As for team two, you’ll find it venturing from Caltrain to the Ferry Building, Justin Herman Plaza, the Embarcadero BART station and the Financial District between the hours of 7:30 a.m. and 11:30 a.m.
