What idiots, well unless they asked what you wanted first. But if not, they were idiots. Want salad? Get salad. Want ribs? Get ribs? Want the kiddy platter of mac & cheese? Get that! Eat what the hell you want.
Oh, and you are an adult. You can order your food. Hell, that was almost the first independent thing my ex-wife, and I had our kids to do — order their meals when we went out. We would read the menu to them, then encourage them to tell the waitstaff what they wanted. Then, when they could read, they wouldn’t even take suggestions. They wanted what they wanted. Which led to some odd meals of kids eating appetizers rather than kiddy meals when they were pre-teens, but that worked for us.
