Great thread
@Tomoreno - for me its simple, life happens and we get it - if you are late - you still have to pay the full amount (this is a no brainer as this was already planned and confirmed) but when you arrive - be honest, ginuwine and most importantly - be kind to the SP - letting them know what happened and whatever time you have - communicate between the both of you what can be done to max. the time still left.
Personally I have been late only once, and when I got there - without any questions I put my payment down and gave my apology of what happened, I even re-iterated that because I was late there is no pressure to do anything if you feel we don't have enough time, instead I will a drink with you if you like, and be on my way. She literally gave me one of the sweetest kisses because no other guy has ever done that before. Had a drink and left, but before I left - she made sure if I book with her next that she will only charge me for an hour for a 2-hour session. That 2- hour was amazing. Being late happens Gents - its how we approach the situation that yields the most rewards.
BTW - haven't been late since - now I probably jinxed myself
. All seriousness though - kindness goes a long way.
