not to diss bike salesmen but I'm sure most of them aren't going to spend the extra time trying to find the perfect bike for someone and possibly risk losing a sale. Stand-over is an ok indicator for pretty much anyone who isn't a gorilla or a t-rex. Apes and dinosaurs should expect more work finding a bike that fits perfectly.

but I think I understand what you're saying and I agree that "misleading" people into thinking that correct standover = bike! is a little shady.
