Need some tips visiting for the second time

I’m visiting from the U.S. and I think I got ripped off yesterday. I paid 100 euros plus 50 euros for a blowjob without a condom. Also, why did she try to rush me in the middle by saying ‘cum baby’ after 10 minutes?I thought I was getting 30 minutes uninterrupted. I’ll be going back again tonight how much is the standard rate, plus extras like without a condom, etc.?
