Amp Dallas/Harry. Hines/walnut hill question

What's the damage/donation for these AMPs that are full menu. I'm trying to get an idea.
140 for half an hour and 200 for a full hour is the going rate.
Thanks sir
Last time I went to Red Rose and asked for 30 minutes, mamasan told me rates were now $150. Seldom do I get a half hour session. So I just paid it. I should have called BS.
