How these shops do business?

Me and my colleague went to this malay shop for lunch yesterday afternoon. It was 1pm, a lot of ppl there. We can get mixed rice/nasi lemak and also order goreng stuff. So a colleague of mine try their mixed rice and the rest of us order goreng stuff. 3 minutes later, the person that took our order came back to us and told us..

W: waiter, U: us
W: Itu goreng goreng tak da la.. sedang potong potong..
U: har? potong potong? nak berapa lama?
W: tak tau la...lama la...

it's 1pm and the cook still potong potong? no need to do business ar? normal days we order goreng stuff also need to wait quite long, if today we wait some more i think 1 hour our food also not yet arrive lar.. sometimes i really don't understand how these ppl do business la.. got money dowan to earn like that...
