A note posted at a gas pump indicates the pump is out of premium gasoline at a Costco Warehouse fuel station, Tuesday, May 11, 2021, in Ridgeland, Miss. State officials warn that any shortages seen at individual gas stations are a result of people "panic buying," and not the Colonial Pipeline shutdown itself. They call on residents to limit unnecessary travel and to only buy as much gasoline as they need. (AP Photo/Rogelio V. Solis)
