Haha, I don't know why you are writing about Trump but no: I don't trust him or anybody else but I think that's because I'm a very skeptical person.

I think the problem with long waiting queues at cash-registers isn't the amount of different coins but the people that 1) do not calculate what the need to pay 2) want to speak with the sellers because they have nobody else they can speak to

But that's all a thing of personal attitude: Do we always have to be fast at everything what we do? Do we always need to optimize everything and use every free minute? In my opinion the laxness comes with age and who knows if we will do the same things in some years that we are hating others for today?
