I don’t see any kind of disadvantage to the club having 3.5-4K sold money tickets (who are likely to buy stuff from kiosk, cooper, programmes) and then giving away the rest of the tickets who would do the same most likely as above. You’d rather the tickets were used up than a more than half empty stadium. It’s always possible aswell that they kids who came last week may see the 20 quid season ticket and get one.
