I love it at my David Lloyd's on a Thursday evening when they come around and tell the men it's time to get out. They are so fucking dominant in there - I would say the vibe is not dissimilar to when a stag do get on the train and you just feel your heart sink. Manspreading, phones being played out loud, loud conversations, hogging facilities. I actually haven't noticed particularly lecherous behaviour at mine, but ugh I just hate them in there.
I never would have thought I'd be such an advocate of the female only hours but god you should feel the vibe shift when they go.
I see the issues with equal access/getting what you pay for. So if we need to give the men 2 hours a week to stop the complaint then go for it I say!
The alternative would be for David Lloyd to properly enforce spa etiquette - no phones allowed, silence, time limit on using facilities, shower (with soap!) before going.
