It doesn't seem like he was kicked out, he could have taken the jacket off. While I don't agree with what happened I can understand how a business that has problems with such things would stick to the rule without exception for fear of being sued. If they start deciding what type of patch is OK and which is not-- there no doubt will be somebody that screams discrimination.
Okay, let’s do this. Take KFC and Taco Bell off the list too as they all belong to the same corporate.
Stop trying to be nice. This “manager” is a complete and utter moron and the “rule” the owner put in is stupid beyond belief. Best to expose this sham and let them close the place due to lack of customers.
Then the owner can take a financial hit. Only a moron would do this.
