For me these days, 100% pay in full up front whether it was a RnT quickie or the works , so the lady knew exactly what I want for the day.
And I also do my due diligence up front if it was my first time with the ML, eg. Making sure the $50 is enough for a nude HJ, or the $70 will include breasts slides = Spanish (like when I saw 38 G Cups Anna the first time…….haha) . Etc Etc.
Cheers
