Ticket Office

How exactly does the 'ticket office' work? How much does it make on tickets per game
On competition matches, you sell as many tickets as you have fans (it's a kind world, every fan come to see you every match ^^)
ok but what i want to know is how much is each ticket? if you have 1000 fans u sell 1000 tickets, so if your ticket office is at lvl11 it say 15 under the level, so is every ticket u sell $15, so you make $15 000 on tickets?
Yes, that's it
Is that also for league games?
