Devils Advocate for a moment considering the woman in Pittsburgh manhandled by the Arab pizza shop manager. That manager was criticized for taking matters into his own hands instead of calling the police to handle. One of the arguments made was that he would have never put his hands on a man like he did that woman and so he should have called police.
In this case the Starbucks manager did call police after the two men who weren't buying anything refused to leave. Granted that manager didn't use common sense and sound judgement. He could have acquiesced and let them use the restroom and wait for whomever they were to meet there. Still though, he asked them to leave and they refused. Why not step outside the store then file a complaint, go to social media or whatever. Was it raining or something? The officers came and they still wouldn't leave. The irony of getting arrested by a Black officer at that.
I'm sorry but I think all the parties involved sans the police acted retarded in this instance.
