Good Lord.....don't you have any place you need to get to?
This is me. I walk fast. I drive fast. I want to get where I'm going quite quickly so I can do the things I'm going there for.
I'm not driving to the hardware store so I can spend my time getting there, I need something there and I need to get back to use that thing. Or walking - I'm not in the grocery store to amble around on vacation seeing all the neat sights, I'm there to get stuff so I can go home and cook.
I cannot stand people who spend MY TIME dickering around doing their little piddlefart things. You want to go slow? Fine, OK, go slow.
But get the hell out of my way.
