It's honestly been ages since I visited a Chick-fil-a firsthand. Originally it was because their sandwiches were tiny and a poor value for a fast food restaurant. After their founder made some discriminatory comments I was curious to see what the business itself had to say. Originally they said that anyone and everyone was welcome in their stores, which I believe to be true, however it was also investigated and reported that the business had been quietly funding discriminatory groups and activists for many years and that kind of sealed the door for me. That's not a problem when you're selling food in a place like Texas. In fact Chick-fil-a's sales skyrocketed in response to their founder's comments and funding revelations down here. However, such divisive positions and initiatives would seem to be a poor match for a pro-inclusion and anti-discrimination business like Amtrak.
OK we're talking about Chick-fil-a's OWNER'S opposition to LGBT equality, specifically marriage equality, prior to the Supreme Court decision in 2015. And his longstanding habit of supporting politicians and advocacy groups who likewise are anti-equality.
It's his right to do so. It's the right of people who don't like what he's doing--and he's very proud of that fact--to not support his business with their dollars.
But he should go all in, I think. If he has that much disdain for gay people, he should refuse to knowingly take their dollars. Of course he won't go that far!
To keep this on-topic, I ate there once before all this came to light. Didn't find the sandwich or their coffee to be worth a premium price. Kind of mediocre. Glad Amtrak didn't make Chick-fil-a one of its vendors.
