I find a super nutrient food bar wrapped in solid gold on the ground. I get healed and get rich enough to start a business. 

The next user is wandering in the city... at night when almost no one is out. The next user is a hobo that sees a guy walk with a super large bag of dollar bills ride the elevator up to the 120th floor of a skyscraper. The next user is stupid and grabs onto the elevator and their hand slips on the top floor so the fall down plumpiting 120 floors. They are a normal human with nothing to save them/use to save themselves, everyone doesn't want to save a hobo and they can't grab onto a floor or something. Also there is no elevator below and there's super acid at the bottom 

Fortunately, I managed to grab onto the elevator's cable before I had accelerated to much. I then force open one of the elevator doors to get out of the shaft.

The next user is a pile of nitrogen triiodide about to be stepped on. You are so unstable,that you will explode if you are touched by a feather, or even air currents.

Fortunately, I am damp, making me stable. They step on me (lightly). It hurts, but not too much.

The next user steps on a large pile of dry nitrogen triiodide

I am no expert of nitrogen triiodide, but based on some random websites:

The nitrogen triiodide was pure NI3, stored in a vacuum and under -30 degrees. I had a space suit.

The next user steps on a pile of acetone peroxide.

For some reason, I was in space and had a space suit. It was too cold and not enough friction was made for an explosion. (if this doesn't work, blame wikipeda)

The next user is trapped in the dimension of infinite homework, causing them to die from boredrom.

You are a NORMAL HUMAN in every way.

Seriously.

And you have a very short attention span, and there is nothing to entertain you.

If you try to do stuff with the homework thats not homework, the stuff turns into more homework.

And you have a pencil to do it ._.

My lead snaps. I have no sharpener - and no way do do all my homework. I flunk out of my Infinite Dimension of Homework class, and my reputation at the Nonexistent Dimensions University is destroyed.

Despite all that, I am still in luck. Miraculously, the slight energy released by the snapping of my lead was enough to destabilize the entire dimension. It ruptures and I slip through the burst back into the next dimension, just as the homework dimension collapses behind me.

This next dimension is fairly similar to ours, but with dragons.

Hell yeah.

The next user is unfortunate enough to have somehow angered one. Their head is crushed by the beast's massively powerful bite, and they are subsequently sprayed with a burning miasma of organic compounds, reprocessed in the dragon's stomach to make an extremely flammable fuel.

Fortunately, it turns out that dragons are especially weak against dry ice, which I happen to have. I throw a block of dry ice into the dragon's mouth, which causes severe frostbite, the pain of which stops the dragon's attack. In addition, the carbon dioxide from the sublimating dry ice prevents the dragon's fire breathing ability from functioning. I then walk away.

The next user is a snowball which has been teleported to the surface of Venus.

I do crap and get myself banned, so I get teleported back into the real world.

The next user thought it was a good idea to have cookies and...

cyinide.

They are a normal human.

And the fact that I spelled it wrong doesn't count, you know what it means.

Fortunately, it was sodium ferrocyanide, which is a relatively non-toxic substance due to the iron atom in it. As a result, nothing happens.

The next user is in a similar situation, except instead of sodium ferrocyanide, it is potassium cyanide which is on their cookies, and it is extremely toxic.
