It's a very common thing with AD turnarounds, new AD's like to bring in their "OWN" people" nothing new with that & you get booted no matter how good you think you are,....It's their loss IMO, & most dont care anyway they just want to keep in budget and fill the entertainment slots per month so they look like they are doing their jobs, most ride on a high horse and don't even show up to the shows they just sending in just the assistant AD's to do all the work at the gig,,...............most times they move to a new facility and will call you to play there no biggie because they now you, ....
it's a never-ending cycle with AD's....and then wait 30 to 90 days for your $$$$
who cares?..... there so many NH places to play,...just move on to the next NH.
One OUT & Another IN simple..

Good luck.
