Are you planning to make coffee at all?
Probably too big an ask (machine, supplies and baristi), but would be a great chance to showcase some CS brown.
I would suggest a printed backdrop of the CS membership card if possible.
Failing that, just the web address and logo in a number of places.
Will the artwork on the van be done by then?
Ill bring the BBQ drum in if you like. Ill even give it a clean.
No need for the rubber chicken now!
