This had happen to me once were a client came back within hours, I got on so well with him, we ended up spending
most of the day together. Think he would have made an awesome boyfriend.
I have had few clients extend time with me, the first time it happen, I was lying in bed having wine with a client, and he suggested to go get some lunch, (here is me with 3 glasses of wine at that stage, wearing suspenders and a big smile) I ignored the preposition as I thought he was not serious. Then he again suggested paying, in a polite way, we came to an agreement, I got out of the suspenders, put on my Levi's, and gucci blazer & we were out enjoying an afternoon, then night that consumed us both. So this was by far the most impulsive.
Lastly, I went to see an Australian client in dublin, and we got on so well, he was so cute, educated and he had ice champagne ready, after 3 bottles, and lots of chatting, I remember being in his bed making, out,and then asked him to get water, All I remember after that was getting up at 7am, and hearing him snoring next to me, Had a beautiful morning-glory with him, and did the walk of shame.... This comfort I would never, ever let happen again, lucky for me he was a gentleman
