An ambulance worker said she feared running out of fuel while on emergency calls due to petrol panic buyers - and was then abused when she finally got some.
Becky Hough was driving around for two days as she neared an empty tank but found queues on forecourts and petrol stations already sold out.
The 24-year-old apprentice emergency care assistant - who works with paramedics - tweeted about her ordeal.
She was hit with a barrage of criticism saying her ambulance has a big fuel tank and she shouldn't have got so low.
Others cruelly said emergency services should not be using normal petrol stations and should have their own pumps.

Ms Hough works for Bristol Ambulance Emergency Medical Services - which provides independent ambulances to private patients, private health care providers and NHS.
She started looking for fuel on Friday and was only finally able to fill her tank on Sunday afternoon when a BP garage let her use their reserves.
But when she finally got some she said was verbally abused and sworn at by other angry motorists.
