I'll make this quick Winded. You can hum a few bars meantime. I haven't traveled since 2008 because I work, very hard and am not rich. I do know of 2 cases in my business network of denied access to long time abusers.I do my best work in the morning....
Your experience does not guarantee others will be stopped. That letter could certainly be needed on your next trip.
No one said it's guaranteed. Has it happened, yes.
I normally do interviews after business hours Winded, but hopefully this tid bit will satisfy your chisme quota for now.
Make it a great day!
