Pastor Rejected The Idea Of Paying 18% Tip To Waitress

A story earlier this week went viral about a pastor who refuses to pay 18%  as tip on a restaurant bill and he wrote " I give God 10%, why do you get 18%" The waitress who posted the receipt online has been fired by her employer.

What do you think...
Was the pastor wrong?
Was the decision to Fire the waitress fair?
