Welcome to OCDO! Glad your first trip out was uneventful, and you were able to overcome the nervousness quickly. For the most part, people don't notice, and those who do will pretend they didn't see it, but just keep glancing at it while they decide to say something about it. I've had a few cashiers do that, and I just go about my business as normal. If you keep doing it everyday for a month, you'll feel naked without it on, at least I do, and I've only been OC'ing since the start of this year.
