What is the typical "tribute" for a dinner date? Only dinner. Please don't respond with it all depends. I realize that but there has to be a going rate.
There is no "typical" going rate. That's like asking what the going rate is for photographers. It's the same answer. It depends. If you want Annie Leibovitz to take pictures for you, it's going to cost a lot more than your friend taking the same pictures.
Like other similar things, the cost is what the buyer is willing to pay. Going to dinner with a professional escort will cost a ton more than an amateur. Professional escorts may charge you as much as $1000 per hour, yes, even for dinner. Dancers are generally not professional escorts and would be happy to get $50-$300 per hour. But remember, this is establishing a per hour cost with her for any future encounters you will have with her.
If you ask how much, that will indicate to the dancer that you are willing to pay. But depending on your relationship with the dancer, she may expect you to pay for her time. If you have paid for other things, you have already set that up with your previous actions.
What you should consider is the following: What is your end goal? If it is just have dinner with her, paying for her time would be the proper thing to do. If it's a meeting to discuss what else might be on the menu, you may or may not be expected to pay for her time depending on your past experience with her. The way you approach her with your proposition will indicate to her what she should expect from you.
Executive summary: Depends.
