Did they measure your shoulders and discuss how your shoulder width corresponds with your handlebar width?

(My apologies in that I haven't had to troubleshoot this specifically, but just fyi, I am 5' 4 1/2", with short arms and torso, and have a 50 frame. My bike came with handlebars that were way too narrow for me, though, so had to switch to wider ones. Just another parameter to consider... )
