I'm going to repeat myself here. As interesting as this story is, the only proof we have that she worked in "a Dallas-are nightclub" is the word of a former classmate who "briefly dated" her, & said LEK "had more problems than he could deal with". Was this former classmate a disgruntled ex-lover who was still upset because LEK wouldn't sleep with him? Or was he someone more sympathetic to her, but her "problems" drove him away? (Either are possible; he wouldn't be the first guy to talk trash about a woman who didn't sleep with him. And if he actually did have her best interests at heart, he wouldn't be the first "nice guy" who decided he didn't have the time for a walking trainwreck of a person.
Velling may have given it some credence because he couldn't find any earnings for LEK during those years. (Which might be because she was still living & working under her birth name.) And because a lot of the cases he deals with involve people who perform that kind of work from time to time.
For an item that is covered in less than 50 words, this one detail has received a lot of attention. Some people have even read into this one tidbit a long, sordid past for LEK. Even if there is some truth in his recollection (& he hadn't confused her with someone else), she might have done it briefly entirely out of desperation for money.
FWIW, a former member who worked as a stripper (she posted under the username AstroKitty) was of the opinion she never worked as a "dancer". Based on her experience, & what was known of LEK, LEK didn't have the personality or social skills needed to make it work for more than a brief period of time.
