I'm glad she isn't claiming a gluten allergy, as some do. Allergies and intolerances are very different things, but some intolerant people seem to think that saying "allergy" is the only way to get other people's attention, and get quite huffy if anyone suggests otherwise. (Yes, I've had customers...
)
To be more precise, my friend has
Celiac Disease - which is basically a very severe case of gluten intolerance, and is sometimes categorized as an auto-immune disorder.
So, unless she really wants to double over due to gastro-intestinal pains, she really does have to be careful about ingesting any gluten. Thankfully, she's one of the "sane Celiacs" - there are some truly almost-militant ones out there. Her gluten intolerance hasn't made her intolerant to other people - or vice versa.

*And did you know that Ghirardelli White Chocolate Chips contain gluten?!?!?!
**Which is the reason why she couldn't have the "Snowy Chocolate" gelato at Cones after our risotto fest.
