Everyone has the odd “oops” moment.
I may or may not have reversed into the main airside/landside differentiating fence at Gatwick Airport once… 
Also reversed into a telephone pole when turning around after fire brigade closed the road putting a house fire out.
Anyone who says they haven’t had an “oops” moment is a liar.
As new drivers, you take on crap paying jobs to get experience.
Employers offer crap paying jobs as they expect the odd bump, so the pay rate savings offsets the risk.
