I may regret asking this but how is this an indicator Wasps are broke?
When I'm broke and someone offers to loan me money I say yes. When I'm not broke and someone offers to loan me money I say no.
At a guess, Sam's perspective is that CCFC offered to pay
some of the costs of laying a new pitch, not
all of them; accordingly, from Wasps' point of view, it's less of a generous offer of financial assistance, and more of a bill for thousands of pounds that the Club may (or may not) be unable to afford.
Either that, or it's confirmation bias in action!
