I had a similar situation last year after working a small pub for over 2yrs, I was asked to take a break as times where hard, I later found out that another dj had approached the boss and offered to do the job for half price, this bothered me for a long time but as I wasn’t enjoying the venue I’m now over that matter and the place in question is now less busy then before, I would say try not to take it personally the boss or owners are penny pinching, something better will more then likely come up for you.
