They didn't have enough cash to hand. They also wanted to use the expired shipping container as storage for tools and as a workshop storage. The Quonset hut, even in small kit form, needs hard standing to be built on. In order for that to happen they will need concrete which means they need water.
Water they refuse to get because in order for a bore drilling company to get out there and actually make a bore hole, it needs a water tanker to help keep the drill bit cooled. Something they responded to like angry chimps by yelling at the bore guy, who presumably has experience and knows what the fuck he's doing "The fuck do you think we're hiring you for?" or words to that effect.
By the by, I have
zero experience drilling bore holes myself, I just looked shit up on the internet. Something the orgres can't be arsed to do despite the fact one of them worked for fucking Google.
Because they were stealing the money you fucking spastic.
