You only see the board advertiser’s on match day Cass why would they need a refund or want one.
Training days, restaurant days, shopping days, stadium tour days. People pay for exposure.
What are you talking about??? None of those things happen currently, people pay for matchday advertising…NOTHING else! So there is no reason anyone would ask for a refund!
Same applies to the stadium naming rights mentioned on another thread, training elsewhere has zero impact on what the stadium is called.
