We don't need to get rid of booth babes to make women more comfortable. The complaints aren't that they exist, but the way they are employed and the fashion in which they dress.
Regardless, being told to put clothes on or move locations is not dehumanising them. It's a reflection of the terrible choices made by the employers, as they're the ones setting the mandate. And honestly, these women were hired to be T&A and surrendered a good chunk of their autonomy in doing so. The superficial argument Jim makes is that there's even no evidence that they don't like it. Well, if it's safe to assume they're okay with it, they have no right to complain that they're being asked to cover up in a private expo.
Either way, pick a side: free will or "just following orders." You cannot have it both ways.
