Jam caused by $1 receipt

It's 4.30 pm. We decided to have an early dinner at Sakae Sushi Festival Market. There's always car park available except for the few days before Chinese New Year. However, there's an usual Jam today. Cars backed all the way to the road outside the mall. While the rest of the cars waited for the jam to clear, a few of them including myself had alighted to check out what's preventing the mercedes from getting passed the car park barrier . To everybody's shock, the barrier did not malfunction. It was lifted up and cars can drive through and enter the car park. However, the E200 Mercedes with a 3 digit car plate number which looked like a bid number, refused to drive through. I heard that the driver insisted that she will not drive through unless the machine print out the receipt for her. The receipt will entitle the holder to a $1 rebate at NTUC for purchase above $100. People were frustrated with her. The queue got longer and after 10 to 15 min 3 security guards still couldn't get the machine to print out the receipt for her. Annoyed drivers started offering her $1 to stop inconveniencing the rest. She refused and insisted the receipt must come from the machine. In the end someone insisted that she had to reverse her car out of the entry point to wait for her receipt. To do so, a few cars had to reverse and make way for her to get out. Drivers casted her a disgusted look when they drove pass her.
