Justifiable?

This morning at Starbucks I was in line behind a pair of medical office personnel who'd obviously never been to Starbucks before. They'd been given the task of fetching drinks for half of Campbell, it seems, or at least for their entire collection of coworkers.

This is not the problem.

The problem is that rather than giving the baristas the entire list of drinks, and then having her itemize the receipt, they ordered one drink, then paid for it, then ordered the next drink, and paid for it, and continued this process until twenty drinks had been purchased.

Then, they had to be told which of the drinks being passed over the bar were, in fact, theirs.

By the time my turn came, I was ready to slug them.

It was justifiable, don't you think?
