I agree that if a girl wants to go out like that, fair play to her. But having that as a work uniform is fairly shit. There are girls who have had a shit day, feel tired, whatever. This place tarts them up to sell more booze, regardless of how they feel.
I have no issue with a girl who heads out for the night in a corset and short shorts. I have an issue with a venue which has four girls, all wearing the same, hawking drinks round the tables.
Edit to add: I'm not sure I entirely understand what the word corset means.
