Every Friday I go to the vegetable markets. It is the central distribution point for all fruit, veg and flowers for the whole of Sydney and it is open to the public every day but there is a parking fee and purchases have to be made by the carton. On Fridays there is no parking fee after 9.30 am and retail quantities are the order of the day. Prices are about half what you would expect to pay in a large supermarket so Friday is a busy day.
The markets are the only place I have ever experienced where retail customers shop in a genuinely wholesale environment. This is a place which has a fleet of rubbish trucks and over 900 forklifts so the addition of live music is a little unexpected but just sometimes there is a singer or band juxtaposed with the utility of the setting.
I don't know who they were but this was today's offering.
