Hope they don't make me walk in a straight line to see if I'm drunk, can't walk straight when I'm sober.
And me? It is not depend on the drunk level how curvy I walk the straight line. Walking straight is a problem for me even with no alc in the blood.
Remember to keep a pack of chewing gum handy to hide the breath, and if they ask to walk a straight line just pick one of the many curvy lines going around trees and lamp posts.
