I didn't get stood up or anything, but man did I have a day of misadventures.
Provider #1: Just got yelled at by a provider. This was because she assumed outcall without me indicating that and when I tried to rectify this by offering a later time for her to make incall arrangements, she said I was making her uncomfortable and proceeded to yell at me, becoming angrier when I called it off.
Provider #2: Only accepts something called Cash Paks that you apparently get at Kum & Go. So I went and asked for that and they gave me what I later realized was a money order.
Provider #3: Works with another provider who mostly answers the phone. Something about needing some time to arrange a babysitter was said and I called back an hour later, at which point I was told she was busy.
Many other providers simply never answered my calls or texts.
Some days you just can't catch a break, despite being willing to go up to 250 on the donation rate.
