All punters are potential kidnappers, murderers, rapists and general arseholes, just like everybody else in the universe from your partner to your postman. Your job is to screen effectively and not see anybody who fails your screening, which for me would include them trying to 'insist' on anything.

As for 'meeting place', if this isn't their hotel room or actual residence how do you propose to check the person actually is where they're claiming to be?

Personally I only do outcalls to hotels or apartments where other people could hear me scream, or another escort vouches for the client. I have strict criteria for outcalls that differs massively from my incalls.
