TREATED AS A *****

I went to a pick n pay family store this morning to buy their nice dagwood, i paid as procedure and went to que for my food. The lady who makes the breakfast checks my till slip as usual and serves me, at the door the security lady asked for the till slip again and I told her I forgot it by the lady who serves breakfast if its too much she must ask the lady i was paying to who was not even 5steps away. The security grabbed me by my hand and my food fell on the ground. I then requested to speak to the manager who could not even understand my anger, they told how they fired staff because they were working with customers and were loosing stock. I work in a reputable Bank, the humiliation and embarassment was beyond measure as people know me, one person even came to my workplace and asked me why was I held by the security at Pick n Pay. The manager showed me a sign that read as follows: \Your till slip serves as a guarantee for exchange and refunds". According to my understanding this serves as when you want an exchange or refund"
