Trixie wasn't always a quadruple amputee. In life she was a waitress, all that running around carrying plates wore her out and ground her down. She'd usually be serving jerks like you, who slapped her ass and gave her crappy tips with even crappier pick up lines. She'd have to smile and take it or lose her job.
Now that Trixie is one of the walking dead....er crawling dead she can have her cake and eat your guts. She had both arms and legs removed so she never has to lift a finger again...instead she is waited on hand and foot and lives an afterlife of luxury.
And don't be all suave thinking she is even going to give you a second look, all the tips in the world won't get you anywhere.
