Rita Castillo, who has worked at the Shell station in Woodstock for about five years, said a glitch in the system Sunday night led to gas being sold for $0.01 per gallon instead of the intended price of $3.50 per gallon, WBBM NewsRadio, Chicago, reported Tuesday.
Castillo said there were long lines of cars waiting when she arrived for work.
"The first thing I do is run outside and check the price," Castillo said.
She said the price was returned to normal Sunday night. She said she does not know how many people purchased gas for the nearly free price.
Castillo said she hopes Shell will make up for her boss' lost product and income.
"I like my boss. He's a good man. I don't know what's going on. I hope the company replaces that stuff. But I feel upset for him," she said.
