Pocket friendly

I have just finished our lunchtime meal with a group of my friends in one of our favourite eateries in town. The waiter brings in our bill receipt which we are supposed to settle then suddenly everybody is quiet, our eyes wandering on every corner of the well crafted, beautified wall hangings of the hotel. One of my friends asks, how much is the bill? I tell her the total is ksh.15,000, then she calmly and boldly says, 'not so much for you to settle it alone. Mmmh, I am left speechless but to go deep in my pocket for what I hadn't budgeted for, am left penniless but with a lesson learned, always make sure your wallet is friendly enough if you are the type of person who loves hanging out and treating people for parties.
