I did a full revealed inspection at a Shell gas station. When I started to input the information, I realized I was in the wrong place! The one I was supposed to be at was about a quarter of a mile away. And the one I was at was not on the job board for that week.
The next week, that location came up on the job board and I considered leaving it for someone else to do but then I said, no! I'm a moron and I'm going to own up to it! When I reached the counter to make my purchase, the cashier (ne'er too friendly to begin with) gave me a cold look and said "Again?" I laughed and said, "Yep! I wasn't even supposed to be here last week but my brain got stupid! I was supposed to be at xxx so that inspection didn't count." He laughed, too. That's the first time I ever saw him crack a smile so I'm glad I was able to brighten his day.
And, yeah, the check-in function had said I was in the wrong place the first time but it ALWAYS says that so it's an automatic disregard.
