There are many cool revelations in this video. First, there are Starbucks drive-thrus?! But more importantly, Starbucks is accessible and can accommodate people of different abilities! 

Rebecca King, a deaf woman from St. John's, Florida, stopped by a Starbucks to order some drinks, and was struggling to communicate before a barista popped up on screen to read her sign language and sign back. This video was recorded the next day, after they established a rapport. It's quickly gone viral, with other four million view to date. King was delighted, telling First Coast News:

"It is a big deal to (the) deaf community that Starbucks has one now. Nowhere else has that! We all want to have that at every drive-thru in the world."
