I have on numerous occasions gone to meet a friend at a restaurant, sat down, told server I'm expecting a friend. When they ask if I'd like to order anything while waiting I usually say no, I'll wait until friend gets here.
I've never experienced or seen that, ever.
What you did on numerous occasions is extremely RUDE AND INCONSIDERATE.
The acceptable, common courtesy approach is to order a drink or appetizer while you wait for your late-running friend, or go sit in the bar. If it is mealtime you are preventing hungry paying customers from sitting down and enjoying a meal, costing the restaurant $$$$ and getting them undeserved bad reviews for not freeing up the table from the obvious non-customer.
No retail or service outlet I've ever been in or worked for allows people to loiter without paying to use the space, no matter how polite and presentable they may be. Until you order something, you are not a customer. When you refuse to order you make it obvious you are not a customer.
Most actually post signs forbidding restroom use by non-customers due to the insane amount of crazy, druggies and homeless that wander our business sections thanks to the failed political policies of you and yours. It's a matter of security, customer safety, and public health regulations. Druggies frequently shoot up in restrooms and even in the back aisles of stores in Portland.
Anyone, regardless of skin tone, will be asked to leave. They are preventing the business from actualizing it's full profit opportunities, which could cause it to go bankrupt in short order.
If they don't leave quietly, police are called.
Police will cite them for trespassing and warn them they will be arrested if they return.
If they don't go quietly at that point, they are arrested.
These guys refused to order, proving they weren't customers.
These guys refused to leave when asked nicely 3 times.
They wanted to be arrested, so they got arrested.
I have managed retail, pharmacy and motel businesses and have had scores of bums, methheads, shoplifters, crazies, and some people who were just obnoxiously rude or had no legitimate reason to be there trespassed by the police. Probably 85% had a skintone similar to mine.
NOT ONCE DID ANYONE GO VIRAL ON THE INTERNET IN THEIR DEFENSE.
