Wouldn't a non-Earth spaceship have alternative fuel sources unknown to even the NRMA?

Would it be possible for a non-Earth spaceship to convert their engines to run off of Earthen fuel sources?

Would non-Earth spacepeople know the expression "when in Rome do as Rome does"?

Even if they had a similar expression, would it be useful in powering their spaceship?

Couldn't the spaceship imitate locals, who would get the NRMA to organise a tow truck to the nearest garage workshop?

What would the mechanics do when the truck brought in a disguised spaceship?

Wouldn't the mechanics be too busy organising a barbecue get together, selling tickets to their mates at the pub and phoning around to invite people around to see the spaceship, to actually examine it?

Wouldn't they want to keep the spaceship a secret until they examined it?

Don't mechanics usually work in teams for safety reasons when dealing with large objects?

It would be foolish not to work in teams, wouldn't it?

What if the shop had recently taken a budget cut and only had one mechanic on duty?

Wouldn't a lone country mechanic at a community BBQ have rummaged up at least 3 men and a dog to give him a hand with the spaceship?

If you where that mechanic, wouldn't you call for help?

Wouldn't the tow-truck driver, the off-duty NRMA serviceman and a policeman be enough help, or should I call on the dog as well?

Don't you think the dog is too much?
