My parents visited my sister for 2 days. They traveled by a private car, but must have stopped for food along the way. After they have been back, both of them experienced fatigue and cold symptoms. As much as it is normal for them to experience after a trip, I wanted them to rule out COVID early. I have heard that early diagnosis and treatment for COVID at their age can be a life saving difference.

If I experienced the same symptoms here in NL, I’d have also taken a test myself just to be sure that I am not spreading it around.

His decision is rational after he explained the reason to me. However, I wish that reason doesn’t exist and that people can get tested without such concerns.

It does sound rational, but incomplete. The missing piece is the one where he searches for (and hopefully finds) an alternative where he can get tested without increasing risk of infection. For example, tracking down an at-home test (he could have used one of the 1M+ tests that Florida recently allowed to expire).
