McDonald’s installed a new Big Mac ATM at its 540 Commonwealth Avenue location in Boston, and offering the burgers for free in exchange for tweets from the ATM’s large touchscreen display. The promotion will only last from 11:00am to 2:00pm on January 31, 2017 and will dispense classic Big Macs as well as the Mac Jr. and Grand Mac sizes. How cool is this! If you are in the area you can enjoy a free Mac and get a chance to Tweet about it.
