I used to always ask somebody else to order for me, but now I just fight it with confidence and trick my mind. I recently started traveling with my boss who understands my struggle. When we are out to eat, we always talk about what we are getting and for some reason, when I say it to her or anybody else with us, it helps when the waiter/waitress come to ask for our orders. Not sure why, but it's like talking about it prior is practice ordering.
