An experience in the new supermarket

Today,my family and I went to the new 'Giant' supermarket in Tampines.The supermarket is really huge and fully air-condition.My parents brought some bread,canned food,seafood and fruit.We spent almost 15 minutes queueing to pay at the cashier counter as there are many people and it was only the second day,the temporary staffs were not very familiar with the prices of the things.They had to go round asking one another.We are waiting patiently for our turn,while some other customer in front of us are making a fuse saying that the cashier were very slow.I think that they are very rude and should try to wait for their turns.
