I go a step further and poke the hornet's nest. Dude in a dress talking like a homo giving me change at the register, "Thank you sir!". Masculine looking female looking full of feminist anger, "Here ma'am, let me get the door for you!". They/them listed pronouns on it's name tag, I write in "sorry, I'm used to only one person serving me, I'm confused who to tip since you're plural" then leave without tipping and never eat there again.
