Honestly, since these customers were already heavily discounted.. out of respect, they should have tipped according to our regular service price, not the discounted price as I'm only making a quarter of how much they paid for the service which was already discounted 50%.  A lot of people tip me well because I put a lot of effort into what I do even while I've long lost the passion for it and am in between switching careers.  My Salon splits the tip evenly unless costumer says otherwise.
