When Jennifer Hunt and her boyfriend, Chris, pulled into the Total service station in Hindhead, Surrey, they didn't expect to get a baby along with their tank of fuel.
But little Tyler decided the time was just right for his arrival.
As frantic dad Chris called an ambulance on his mobile, the service station's sales assistant Vakeesan Jeyaratnam helped Jennifer, 21, into the shop and closed the garage down.
Baby Tyler popped into the world weighing 6lb 3oz. The happy family were then transferred to the Royal Surrey County Hospital in Guildford, Surrey.
Jennifer told reporters: 'It all happened somewhere between the biscuits and the anti-freeze. It was a lot safer to give birth inside the shop than the car because there was more room. It was quite cold because the air-conditioning was on but I didn't care.
'I started getting twitches at about 10pm the night before. Chris has a night-time job and normally finishes at 2.15am but decided to stay on to do a couple of hours over-time before coming back home at 4.30am. By that time things really started to happen. We were going to drop my other son off with my mum and had arranged to meet her at the petrol station.
'But I realised we weren't going to make it to the hospital so just decided instead to stay at the garage and have him there. I never had a birth plan because things never turn out as you expect, but I never in a million years thought this would happen.'
Jennifer and Chris already have a one-year-old son, Logan.
Proud Jennifer said: 'Everyone is doing well and Tyler is gorgeous. I want to say an extra special thank you to the Total assistant who was brilliant. He couldn't have done more to make what was a very stressful occasion easier.'
