I'd replace the DRS speakers.
(If money was no object, all of the above).
I second that, which you contrive.
On top of that I'd ring fence any miscellaneous potential business streams to remain part of the club for a 999 year lease. Meaning no future (for 999 years) asshole could sell off the catering or continue making misc. profits from the club. They'd be separate entities, "STFCclubshop Ltd" "STFCcatering Ltd" and so on. Everything would still be sourced from the club/remain in-house but the quality, staffing, service etc. would be exceptional.
