Coming back to Spa fun NEED HELP

My last spa adventure was meeting Susan at red rose spa right before covid hit. I asked for half hour session and was ready to pay the usual fee that I had know which was 140 at the time. She looked confused and said that wasn't the correct amount even thought I added a 20 dollar tip for a total of 160 she said it was okay and we had fun anyway. Planning on hitting the spa again, but my question is have the prices risen lately? I don't want to show up and get ripped off or low ball the girls. I don't want to break any rules on here so if you have to DM please do.

P.S Who should I got visit? 🤔
add 20 to previous prices. $.6 and $$.2
Thanks for the help!!
