Yeah, that's about normal. You'd pay more per hour for 1 hour over 2-3, because they've still gotta get dressed, spend the time, travel, and get blasted with your clumpy nut regardless.
Next time, try asking for 2-3 hours up front and it'll likely be closer to 1.5-2k for a 2 hours or so.
Repeat longer visits get the cost down as she gets to know you and knows you're cool.
You know the bitch sees you as a chump if you get the "I'm putting my prices up for everyone" line if you try to rebook. If this happens, just back out.
Make sure you don't seem like you're loaded and don't care about money, because you will pay for it.
In general, be nice, be respectful, but most of all, be fun and NORMAL.
Never heard of this bitch but she looks elite and fresh. Body like a young Amia Miley, but probably knows more exotic food than tequila. Get after them holes bro.
