Dancer turnover?

I stopped by last tuesday night, expecting more of the usual. Older Brazillians, most of whom I expected to have seen before. Instead, I recognized none of the 3 dancers on shift. Two were younger, probably in their 20s and actually pretty cute! The somewhat older (late 30s, I'd guess) third one came up and talked to me for a bit, said she had worked at the Blue Goose before. Ended up getting a dance from one of the younger girls, same extras menu as before, maybe a little less pricey and a lot of fun. I guess I just came by on a good night.
