I wonder what these mums put as their reason for arriving late when they have to sign their kids in at the office. Is it the same excuse every day? Or is it a challenge to think of a new reason each time? Why aren't they embarrassed like I would be?
What's your biggest gripe when it comes to customer service? Automated answering machines? Long wait times? Being shunted from department to department? Being forced to follow up over and over again?
