While I do hate Ticketmaster with a passion, I have to admit that about 6 years ago I went to local venue that had been gobbled up by LiveNation and I was amazed at the transformations they had performed. Bathrooms had actual attendants, people whose job it was to keep the line moving. They would watch stalls and urinals and then tell the next person in line when one was free. Pavilion seating had wait service, so you didn’t actually have to get out of your seat to get an overpriced beer or food. The place was clean, fresh paint was on everything. I was at a concert at this venue last year and it still looked nice and these services hadn’t gone away.

Yeah, that's how it works. The monopoly strangle the dependent company to force them to sell to you. "Vertical integration" they call it. Perhaps if the original owners had a reasonable cut of the money before , they could've provided better amenities.
