What? When did I ever say I suspected to be infected? Confinement procedures aren't for infected people, they're for everyone.Masks aren't perfect, small as the chances are anyone working there meets hundreds of customers; hundreds of chances for the unlikely to happen, and then hundreds of chances to pass it onto someone else. Which is why they say don't go out AT ALL if you suspect you may be infected, and limit your interactions in lockdown as far as possible. Easy way to do that is not pop to the store every few days.
