I have been on a date with a WL in Singapore, once. Saw her twice (paid session) and she asked me out. Her looks were above average, seemed genuinely nice - so I agreed. She took me to a club - paid for my entry and bought me two drinks. Spent the night dancing (read grinding). She asked me back to her place - I declined. Never saw her again, did not want to get attached or develop any feelings.
Since then I have been asked out twice in Sydney, both by ML. Took one ML out for a drink - chatted and that was it. She was a little too candid about her life, and I realised that we have absolutely zero common interests. The other ML - I just never really responded to her request. Again, she was too chatty during the first session and offered FS in second session - that there was nothing left.
My experience might not be something to go by though, I just prefer to keep relationships at a distance with WL and ML.
