First I speak from experience of bad trains with no toilet lids, snapped off flush handles, p!ss in the sink, the odd log. This was last month. OK it was not an intercity but why would i make this up? I was thankfully only wedged next to it for about 15 mins. All the trains I have been on recently have awful toilets.
Also would I tolerate it in a hotel? No because I can do something about it. If your on an aircraft mid ocean then what do you do? You put up with it because you have to. OK if you were on this aircraft what would you do? Moan probably.
Maybe I look at it as a joke- an acceptance that given the amount of action they see sometimes toilets break. But what I think is not acceptable is the state those disabled Iraqi kids were found in last week lying in their own waste through no fault of their own, while the C*nt of a caretaker sells the food meant for them. Then i think a broken toilet so what?
Maybe I just think there are more important things to deal with.
