Pick n Pay local refused to help me to feed a few hungry souls in Parow

I was at Builders Warehouse in Parow Cnr DeLarey and Joubert Street to have a board cut and some of the unemployed people ask me to buy them something to eat so I agreed to buy some rolls for all. I went to the Pick n Pay local and ordered a 100 hamburger rolls which cost R2.50 each. The lady at the bakery counter refused to sell me the large amount and said that I have to order rolls for that amount (I could see that there were enough rolls displayed). I explained to her that I am not from the area and I just saw an opportunity to feed some hungry people. She still refused. I then spoke to the manager and he had the same view so I just walked away. I felt lousy having to explain to a Manager the same thing twice as if I am speaking to a "Spoilt Man Child" and why I needed his help to step up. This was not for a function held outside the Pick n Pay local shop.
