Pit Boss Comps

Whenever in Vegas I usually play at the same casino and have a good relationship with my host there. He is able to help me out on meals, clubs, pools, etc. When visiting other casinos can a pit boss take care of much or should I speak to a host? An example is if I play for 3-4 hours at about 200 a hand can the pit boss take care of a dinner? I am not really interested in a buffet but in some of the nicer restaurants.

I had a pit boss at Taj Mahal give me a dinner coupon once.

But before I used it, I went to a terminal to check my points, and it was totally wrong.

I went to a rewards desk to ask about it. The gal there quickly figured out that the generous pit boss (who had earned a bigger tip for the boys in the process) had actually taken the money out of my account for the 'free' dinner coupon!
