The automated voice for most of those self checkouts are so loud that I become very self conscious when using them. When the other side of the checkout lanes can hear the automated voice, it is time to turn the volume the fuck down. Instead, they might have made them louder instead.
Having worked in retail for a while, most checkers don't give a flying fuck about what you buy or don't. They hate the job and by association, you, so much that they don't care if you're buying a douche, Trojan Minis, or Immodium AD.
