Glenn Lazarus Didn't Love Dinner At The PM's House, Went To Macca's Instead

We've all been out for dinner with friends where we got a meal that we didn't really love, but ate it anyway so as to not cause a fuss -- then went on a cheeky fast food drive-thru run on the way back home.

In that sense, Senator Glenn Lazarus is in touch with the common man today, after admitting he made a pit stop for burgers after an unsatisfactory dinner with the Prime Minister last night.

Lazarus is one of the senate crossbenchers angry at the government after senate voting changes were announced this week that would likely see independent members struggle to be elected in future. Lazarus, Jacqui Lambie, David Leyonhjelm and Ricky Muir would be among those in danger of losing their seats at the next election.

To smooth things over, Turnbull invited the Senate crossbench to a fancy dinner at The Lodge, the PM's official digs in Canberra. Despite threatening to boycott the dinner due to the "nasty" changes, Lazarus ended up attending with Dio Wang, Lambie, Bob Day and Leyonhjelm. Fellow crossbenchers Muir, John Madigan and Nick Xenophon did not turn up.

While Lazarus did eventually soften his stance and attend the dinner, he was left with a sour taste in his mouth, and apparently not enough food in his belly. Speaking on ABC Radio on Friday, Lazarus said the dinner was a "waste of time" after claiming the PM was not able to address his concerns over environmental and tax issues, and apparently even the dinner spread was not up to scratch.

"The food was lovely, don't get me wrong, but portion size was a little on the small size so a diversion to McDonalds on the way home was needed," Lazarus said.

He later expanded on the claim on Twitter.

And again soon after, speaking on Melbourne's 3AW radio:

"We got served a piece of blue-eyed cod, that was gone in two mouthfuls. It was beautiful, don't get me wrong, but geeze, I guess they're cutting corners," he said.
