Please, people, the onus is upon yourself to check your own passport and those of your young kids and elderly people that you bring along.
The officers have to deal with hundreds upon thousands of passports during their shift, while we've only ONE job and that's to check ONE passport. Pay 100% attention to the officer when you're at the counter, stare at what he's doing if you've to.
For them to miss stamping some passports is not something new, not something in line with Covid, nothing to do with the pandemic. Unless you're just born during this pandemic, you should already know that you should check your passport, anywhere in the world.
Check. Your. Own. Passport.
