Similar here. Wanted to dispose of some contents (mostly old crockery & small household bits) in the recycling/reuse shed and was told it was commercial. When asked why, the ol' fella said it was because I rocked up in a pickup. The fella was abrupt & obnoxious, totally full of his own importance; a jobsworth type.
Ended up going to the Northern site the next weekend who actually helped me unload and couldn't have been more helpful.
