Hanging out at a friends house last night.

99% of the time when a theist saws "let's bow our heads" there asking those that want to pray to bow their heads. It's the easiest way to address a group. I know they don't expect everyone to bow their head or pray. Any theist that has kids and tries to get their kids to "bow their head" doesn't really expect the hungry toddler to care or understand talking to God. The toddler simply doesn't care about what they're doing and wants to eat.

I believe you're feeling cognitive dissonance because of the social pressure to not eat so other people can talk to something you don't believe in. What might help you is separating out whether you're pissed they talk to God, or that you feel obligated not to eat right away. Doesn't sound like you were asked to play and not expected to participate. Does people having an option to pray in school bother you as well? Does seeing someone in a restraint praying for their food bother you too?

Having an option to pray doesn't remove your option not to pray. Asking the room to bow their head doesn't mean you have to. Just care less about what they think and when they go to hold your hand while they pray grab a drumstick instead and nod to them As also pointed out, you're the guest and hospitality is a gift and a skill not all have. I don't fix my guests drinks I pint them to the cupboard and fridge. I do try and give them a clean bathroom and variety of drinks and snacks but that's about it.
