Exactly this. If the lunch isn't gluten free AND good, i consider it a request for me to not attend.

Although, if they get pizza, I'll scrape half a pizza's worth of toppings on to a plate and let them see me dropping the crust in the trash. They always ask about dietary restrictions... and they consider shitty pizza shop salad a GF meal?? LOL. I always plan for my own food for events like this.
