I had double vaccine, Omnicron 22 days prior, and tested (viral test at doctor) 12 hours before travelling. Unfortunately, Erin was still sceptical and asked me to take a PCR test, which cost me 150$. After telling the host about the result, she asked to see the official test result herself.
Being afraid of COVID is perfectly respectable, but I wish she had let me know prior to checking in. The whole experience made me feel there was no trust, not friendly and very hostile.
