It's extremely unlikely you're going to get COVID from your bank trip. Many, many healthcare workers treated COVID patients every day for nine months unvaccinated and didn't get COVID. You are vaccinated, it's only half an hour, and it's unlikely that anyone in the bank has COVID. IMO wearing better masks is a great thing, and so is minimizing indoor time with strangers, but it's also possible to overdo COVID protection. Most of the spread of COVID is among unvaccinated people doing things indoors and unmasked. Unfortunately, you being even more careful will not affect their behavior.
