A recent experience I had while bartending: After intently scrutinizing the menu for a few minutes, a women asks me if an item is good or not. It just so happens to be one of my favorites, but when I tell her that she says she needs a little more time to decide.
I walk away, but notice out of the corner of my eye that she has whipped out her smartphone and is now looking at a photo of said menu item online. When I return she asks me about something else that I don't enjoy as much. I answer honestly and the process repeats itself. Eventually she orders the not-as-good thing.
When the food arrives she takes a very long time to eat. She says it's great, but I can tell it's not as good as she hoped it was, which is what I told her in the first place.
The moral of the story? You're not buying a new car here. It's just lunch, a pretty low-risk situation--listen to the person who knows what they're talking about.
