text: The man tried to grab money from the cash register as the clerk opened it.
  Alachua County Sheriff's deputies are searching for a man who tried to rob two gas stations late Monday.
  Employees at Chevron, 7500 W. Newberry Road, and Sunoco, 6800 W. Newberry Road, provided similar descriptions of a man who came into the businesses posing as a customer, said Sheriff's Office spokesman Art Forgey. The man at first claimed he wanted to buy a lighter but then tried to grab money from the cash register as the clerk opened it.
  The robber threatened one employee with what appeared to be a knife, Forgey said. But no one was hurt in either incident.
  Forgey said the suspect didn't get any cash from the first business because the clerk was able to shut the cash register drawer before he could grab any money. He fled with an undisclosed amount of money from the second store.
  The man was seen driving a dark, older-model sport utility vehicle, possibly a dark green GMC, Forgey said.
  The first robbery occurred just before 11 p.m. and the second about 45 minutes later several blocks away from the location of the first incident, Forgey said.
