And aren't they annoying? People who spend unnecessary lenght of time at a cashier, paying with a credit card something worth 50 cents, when they could quickly hand over a coin or single note to pay for it.

I do find it annoying of others, but this is what I find especially funny: I do the same damn thing. Yep... I am that guy.

Invariably, it is the really cheap purchases where find that I do not have cash on hand. Sometimes, the credit slip printer jams, too, or the debit terminal has a convoluted series of questions that prolongs the transaction even further. And, then I find myself chatting up the cashier in the extra time, which slows everything down even more.

But, there is a plus side to it. I will likely not get shorted on change because of a dishonest or distracted cashier.

. . .or one that speaks horribly broken English,or can't do simple math.
