I've had quite a few of those. I guess the very best one was when I'd driven 16 hours and checked into a hotel way after midnight. My father and and little dog were with me, and it took quite a while to find a decent place that would allow dogs.
We were all so weary, and had to be up very early to attend the memorial service. I mentioned that we were there for my aunt's funeral, and when checking out I saw that we were not charged for the first night.
I received two national geography guy at my reception desk. they disclosed when they checked out XD
I've never had any problems with my service. But just last week I received a $95.00 refund from Spectrum, because they had overcharged me, I didn't even know it. lol
