What Constitutes A ROB?

What are things a dancer does that gets you to label her a ROB, or rip off bitch, in a review?

Here is a starter list:

1. Agrees to services up front and then does not deliver in the private dance/VIP areas. This could be extras or something as simple as her saying you can touch her in private, then will renege or demand an upcharge once the session begins.
2. Overcounts songs in post-pay situations. For example, you do four songs and she says it was six songs.
3. Undercounts songs in pre-pay situations. Similarly, you may prepay for a thirty minute VIP and then she stops at twenty minutes and says it has been thirty minutes.
4. She wants to be pre-paid in a club where post-pay is standard procedure.
5. She charges more than the posted rate for private dances and does not bother to tell you this beforehand, but after you have finished. She may say, "Dances are $25 per song, but I charge $35 per song."
6. She puts extremely low effort into the private dances or VIP. She tries to make it "paid conversation time" instead of giving lap dances.

What other tactics would you add to the list?
