I request etransfers when I tour of about 50 bucks which goes toward their booking. Once recently I had to cancel a tour to Calgary, just not enough interest to go and make it worth it $$, so I refunded back the 3 gents their deposits. I would never ruin my rep for 50 bucks just not worth it.
Here in Winnipeg I started asking for deposits for gents who want to meet on a day I am not available, before I recently found a incall I was renting hotels one gent who I saw once before said he wanted to meet up. So I booked a hotel for 180ish after taxes. He no showed, hasn't even called to apologise till this day.
It's been said many times, DO YOUR RESEACH BEFORE YOU SEE ANY SP. Check to see if they have a webpage, any reviews, if they have a social page like Twitter, is it active or do they have followers, recent pics etc.
I don't have time in my life to search anyone's name to try and black mail them. Also with etransfers you could send it by cell phone or by email. On bank settings you change your gmail account to the one your using on here. Just remember to set it back.
Some don't want traces on their account, ok I get that. There is always old fashion Money Mart.
Cheers
