If you publicly announce you’re going to be a jerk, expect it to be commented on.

You choose how you’re going to respond - don’t give the information, but there’s no reason to take it out on the lowly worker.

I was merely explaining my resons in case anyone did not understand my motivation.

I’m sorry that you think of yourself as a lowly worker. Have you considered therapy to combat your low self esteem?

Your right. THEY ARE ONLY FOLLOWING ORDERS. Hmmmm.

... but there’s no reason to take it out on the lowly worker.

There's almost never a reason to "take it out" on the lowly worker, as long as they are trying their best and being polite about it. It's ungracious and without class to treat service people badly. They're usually working in a sh!ty job, getting sh!ty pay, with a sh!ty boss, with no power to fight back against those who may mistreat them, and they are usually providing you with some kind of essential service, no matter how trivial that service may be. You should be thanking God that you aren't having to do their job. In a worst case scenario, you can politely ask to speak to their supervisor for help if they are completely clueless, and you really, really need whatever it is that they are trying to provide you.
