A hooker will dispense with even the appearance of any other than sex for money.
A good rule of thumb, if a "Sugar Baby" agrees to meet you anyone of these places; her place, your place, or a hotel, she is a hooker and you don't really need to bother with any warm up except agreeing to a price.
If she insists on meeting you for a non sexual date first, she still may or may not be a hooker, but the chances are she wants an "arrangement" and not simply "so much per hour"
It's also been my experience that many of these SB's who insist on a non sexual date first quite often are willing to hop into bed with you on that very same "first date" if they like you. Some of them will even do so for free, actually a surprisingly large percentage of these girls will hop into bed with you for free and you don't "treat" them like a hooker.
I NEVER lead off with any mention of money on my first date with a potential SB. I treat each date just like a civvie date, eventually she will bring up the subject of an "arrangement" if that is what she is looking for. The last thing I want to do is treat a girl who just wants "good company" and to be "treated well" like a hooker and turn her completely off in the process.
A hooker is never going to be "offended" by being treated like a civvy date, a non hooker doing this for the first time can most definitely be turned off by some guy offering her money for sex in the first five minutes of having met him.
