I am always pleased if I am tipped however I feel it's strictly up to the client. It feels good to be tipped knowing that the  individual felt "a good job " was done. A" thank you!!!!" text is also nice . 
  
I know some may lean on the client to tip....don't feel obligated to do so unless you , yourself the client felt it was deserving and prepared with a bit extra in the pocket.  
  
Other than that have fun :) play safe . 
  
Just my 2 cents 
  
Cheers!
