Four incidents, four airlines, all showing the same intolerance for words on a mask or shirt (despite the fact all four customers were in 100% compliance with the letter and intent of the actual TSA/FAA policy).
In three of the cases, the customer was taken off the airplane. In just about every case, the employees made up policy on the fly, and were wrong...
Sorry, but I'm not going to trust "common sense" especially if flying is required for my job.
Due process, and nothing short of that. Period.
