Caroline Mutoko: I Don't Do Cash - I Do Airtime

Like any rational being, I love to appreciate anyone I encounter for their service to me. For a long time, I have always felt that cash was little "tacky" ... but the sheer delight I see on people's faces when I give them data or airtime is simply priceless. That's me, the lady who tips in airtime and not cash. Thank you Safaricom.
