A close group of girl friends and I enjoy getting together for lunch and dinners a few times a month. There are four of us, and every time we sit down and the server introduces themself to ask for our drink requests, the same friend always places her order immediately. (The rest of always say we're not ready and still need to look a the menu.) She's been doing this for years, always says she's in a rush, ...every, single, meal. It's a bit weird, and the servers have always been polite, but usually thrown off a bit by her immediate rush to place her food order.
Just once, I'd appreciate it if she'd not rush the food order and follow the normal sequence. I honestly want to ask if she's ever learned the basics of restaurant etiquette, but don't want to insult her.
How can I politely ask her to wait until it's time to order our meals?
