i did a little math if 6000 fans come to game and each spent $20 on food/drink and there are 11 home games that is $1.32 million coming in a season and personnally i think my $20 is on the low side i spend about $40
The stadium licences a catering company to run the food stalls in the venue. The stadium gets revenue from that, and the catering company, but I don't think the hirer of the stadium would get any.
The only revenue streams directly into Phoenix coffers as far as I know are:
1. Ticket sales
2. Merchandise sales (they get a percentage I believe)
3. Television rights revenue
4. Sponsorship revenue
5. Transfer market revenue
Any other money they need to spend has to come from the owner(s).
but if they, in the last seasons, have been getting extra money coming in via their other investments which they will lose if the Nix fold or move that would be a reason to invest
