Interacting with maybe a dozen people outside with a mask on for a few minutes at a time is almost certainly much lower risk than being in a courtroom with, likely, many more people and stale air for hours. It’s certainly helpful if everybody is masked up in the courtroom, but people are notoriously bad at wearing masks properly and there’s a lot more factors you don’t control in that scenario… outside delivering stuff you can always walk away if somebody isn’t giving you the space you’re comfortable with… Regardless, all risk is cumulative and you may want to limit the number of times you do higher risk things as much as possible. Even if you rarely do some riskier things, it doesn’t mean you’re okay with that level of risk all of the time. I don’t think it’s that unreasonable to want to manage and minimize your exposure if you’re high risk.
