I used to subscribe to the 'no stupid questions' school of thought. But having been in the army, and now teaching this trade, there are indeed stupid questions. Like, I'd rather you ask before crashing my machines, but the fact that you are asking this shows a fundamental lack of understanding the basic concepts of something you supposedly learned a year ago.
Never underestimate what poor hiring practices and a lack of training can do. Way back, I worked at a grocery store and my coworker called me over to help him because he couldn't get an item to scan. It was a potato. Not a potato with a barcode sticker, or in a wrapper or anything like that. Just a fresh, raw, skin-on potato, and he was waving it back and forth over the scanner, completely confounded that nothing was happening.
