We have done a few bin runs for longnecks, which is kinda fun if you don't mind the odd dirty look from the person whose bin you are raiding. Less and less suburbs seem to have the open top black bins, all going over to the lidded type.
Restaurant runs have been patchy- people in St Kilda drink all manner of crap, ended up with a lot of mismatched glassware & some odd sizes too.
Slight, you may like to try the Duke's mates at the Brew Crew- it's on your side of town. Tel. 9563 9232, 50 long necks for $20, clean skinned and sterilised.
