What Comes First?

Well, I typed up this post two days ago and hit some random button on my laptop that deleted practically all of it so I'm a little bitter. It all seems part and parcel to the dark cloud of jinx that Himself and I just can't seem to shake right now. Here's a better explanation than I can give:
Himself Speaks

Anyhooo,

I decided to recreate my accidentally deleted post in haiku:

Sent for groceries
hurrying for mom-in-law
caught up in long line.

Cashier provides change;
receipt, bills, then coins on top,
pyramid crumbles.

Coins splatter on floor
lost to my limited time.
Is cashier stupid?!?

Everybody knows
heaviest goes on bottom,
this is my pet peeve.

Now doing research
at banks, shops, etc
tell me what you think.
