Let me tell you something about America:
We have a document called the Bill Of Rights. It's the first ten amendments to our Constitution. During the constitutional convention, the Constitution wouldn't pass without these ten extra provisions guaranteeing rights to individuals and lower tiers of government. The First Amendment includes the rights of free speech, free press, peaceful assembly, practice of religion and petition. The second protects the right to bear arms. The fifth protects the rights of the accused. From which amendment does congress get the power to enact intellectual property law?
It's a trick question. That's not in an amendment, it's in Article 1. Copyrights, patents and in this case trademarks are more foundational to society than even free speech.
I do prefer franchise or chain rest stops on a long trip, because they have an established reputation. The business owner defends their trademarks largely as a marketing exercise, to prevent competition from stealing their sales by putting the same name on the shelf. The customer wants those trademarks defended because they are powerful tools for accountability. A business does a bad job, avoid their products and services.
I've never gotten food poisoning from a burger chain, I have gotten food poisoning from a "proper" restaurant with a chef. I've never gotten contaminated gas from a Sheetz, I have gotten contaminated gas from Ma And Pa's Kountry Kitchen. If I'm gonna drive across this nation again, I'd rather fill the car with Buccee's gas and eat nothing but McNuggets on the way because that way I'm sure neither the car nor myself will be on the side of a Mojave highway spewing unidentifiable fluids.
