Are your clients stingy or enlightened?

Recently, I went to buy a pair of shoes in one of the leading shoe company outlets. My interest was in a particular pair of shoes but another one caught my eye and I put both pairs in my basket. Mental math showed that my total bill would come to Sh10,000 and I was so impressed with my picks that I walked to the counter with a big grin on my face. Then at the counter, I was asked to pay Sh50 for a bag. I asked the attendant to do some quick math and give me the percentage of the price of the bag from the total amount I was paying. Of course she couldn’t be bothered to do it. I wanted a free bag to go along with my purchases. Ultimately, I walked away not having bought anything. Someone could label me as mean, figure that if I can afford Sh10,000, why not Sh50?
