There were 2 men who refused to order anything to drink or eat. They refused to leave, they used the facilities.
The police were called and asked them 3 times to leave. They refused and were arrested for trespassing.
The police have stood by their guys, rightly so.
This isn't a colour problem. If I was taking up space and not paying for a service, I would expect to get arrested.
No. On paper and an ocean away I can see you point, but hanging out in Starbucks while waiting for a friend isn't really any issue. These were not vagrants and they were not causing a problem.
This was an issue with the employee who called the cops for no valid reason. Not a Starbucks issue, not a cops issue, an employee issue.
Fire him/her and move on.
