Toilets.

Roger comes in arms flapping and frothing at the mouth, nothing unusual about that.

"The units that came out of Indonesia are useless, we should not pay a cent for them"
"What are you talking about?"
"None of them fit, they all have the wrong connections"
"Are we talking about ablution blocks?"
"Yes the McDowell once at Hegigio"
"What's the problem?"
"Three of the four toilets are blocked!"
"So?"
"They have three inch outlets instead of four inch!"
"So?"
"Well the guys that are staying at the camp use a whole roll of toilet paper every time and then flush whole roll card board and all through the toilet"

"Now I understand, I don't think a four inch outlet would make any difference, you better get a plumber"
"OK"
