Just, for a moment, consider the comments to this thread in light of what happens when you go to purchase anything else.

Even your local mini-mart faces economic pressure to let folks use their debit cards for small sales- even though the hidden transaction fees will eat up all the profit for the storekeeper. Nor are folks going to hunt long for a parking space, or tolerate much of a wait in line. For the merchant, it's all about the bottom line.

It's almost a law of the universe that pleasant experiences bring back customers, and happy customers make for a prosperous business.

NOW ... compare that to the practices of anyone that has a monopoly, and the use of their product is mandatory. Whether by law (traffic tickets) or practical reality (the electric or phone company). Long waits, unhappy customers, all manner of impediments for the customer. After all, it's not like your business can go elsewhere.

Let's look at that mini-mart again. Can you imagine the effect a 'no cash' or 'exact change' policy would have on his business? As much as the owner would LOVE to eliminate the burden of maintaining a cash drawer, the daily trip to the bank, and the worries about errors, thefts, and robberies .... the mini-mart still takes cash.

Snafus? Consider the differences in the way private concerns handle customer issues to the way government does. Or, such mundane things as business hours, business location, etc. It appears that the deck is stacked, from the start, against there being a happy relationship.
