That's exactly what I do in Atlantic City.

If I go up to a table and ask for chips they usually look really annoyed and just give whatever is on top.

If I send my petite cutie up there, the pit boss (usually male) will spend all kinds of time trying to pick out exactly what she needs (one time searching for and finding some Tropworld 2.50s at the Tropicana).

Go figure.... (no pun intended)
