Along the same lines, are those that act like it's the most important thing in the world at that exact moment...to immediately answer a ringing cell phone.
While there may be a minuscule % of those waiting for a call that they absolutely need to answer, most people (young & old) act as if there isn't that neat little feature installed in cell phones...called VOICE MAIL.
What did we ever do in the
'olden days' when we didn't have the ability to yap on a phone, when digging for change or coupons...while the cashier and line behind waits for you?
