"Someone got offended and left.
Just give them their money back and move on."

Sounds like an open invitation to freeloaders, if you ask me... Also, I'm not sure I'd want to live in a society where everytime someone decided something had offended them, we had to compensate them. I also don't like the sound of a society where everytime someone didn't get their own way they went mewling to the lawcourts like some great big crybaby.

Lets not support the abdication of one's personal responsibilty to behave like an adult, eh?

And let's not forget that everything being exactly how you want it all the time is a pure stroke of luck, not a right!
