“We have to be here for our community,” said Becky Orero, a former worker at the nightclub who spoke to the Orlando Sentinel. “I made sure that I came down here so our friends and family can make it out okay.”

“You want to do something to help,” Frank Tiffany, who was also in line to donate, told the outlet. “It’s hard to believe. You have to do something to help. You can’t stay home.”
