I think what I find depressing in this day and age is the fact that this type of all male occasion still exists, particulary being dressed up as charity event as if that will somehow mitigate the bad behaviour of some of the guests. Now that those involved are trying to cut associations what does seem puzzling in the afttermath, is the denial that some of the lots put up for bidding during the evening, for example tea with Mark Carney at the Bank of England, or similar with Boris Johnson, apparently didn't exist as they had no knowledge of them.
Some have criticised the expose by the FT journalists as it has resulted in some of the charities turning down the money, nevertheless I think it's not unreasonable to expect charities not to accept money that has derived from someone else's discomfort. I agree with Day 6, a mix of male and female waiters, appropriately dressed would have made the whole evening far more acceptable, but The President's Club promoted it as something along the lines of "the most un PC event of the year" which set the tone 
Overall I blame the agency for not being completely honest with the girls hired. The gig should have been presented to them thus, pointing out that they would be wearing suggestive clothing, they may be hit upon by some of the guests and be able to cope with that but perhaps they didn't because such clarity would mean they would show there was a mild element of pimping involved. However, at least the women could have made a fully informed choice as to whether they wanted to do it or not. Hence, my comment about the derisory sum of £150 for a 4pm to 2am shift. Yes it is a lot compared to say a shift in McDonalds, but not for what was expected in this instance, surely some compensation should be built in to put up with gross conduct.
Unfortunately the criticsm has been conflated with the over the top "Me Too" campaign in what does appear to be a witch hunt against men per se. I think it's just as obnoxious for women to be pawing young men in a similar situation as Grandma 2213 mentioned above. In fact anyone who thinks it's okay to grope staff is a sex pest as far as I'm concerned.
