couldn't find an answer in the noob section.  i am planning a 3hr outcall with a well established/reviewed provider.  menu is all the good stuff including greek.  on TER and personal site price is 600/hr; 1000/2hr; 1500/3hr; 2k/4hr; greek 1hr =1000.  i want our whole date to be 3 hrs and the whole menu available but obviously won't be dining just one cuisine the whole time.  how should i properly arrange my donation?  i am 100% ok with leaving 3k, but i don't know what the accepted convention is without having to talk about it/ask about it (seems to be a no-no).
