OMG, this was definitely SO true of my grandma when she was alive. She would frequently go gambling and the casino gave her free food and she wouldn't eat it. She'd claim she didn't like it, all of it, couldn't stomach it, not even a bite. So she'd pack a lunch.
It kinda bothered me because as far as I'm concerned if food is free as long as it's not rotten/unsanitary or meat (I'm a vegetarian) and I'm hungry, I'll happily eat it, even if it doesn't taste good.
(The casino's food is/was just fine, btw)
