It was great having a BP within 1 kilometre of my home. Like many people before me I had on a couple of occasions in the past 10 years, left my wallet at home and lost my cards. I filled up no realising these mistakes, and filled out a form and within a couple of weeks the amount was repaid. It happened a third time, only once, and again I paid the debt within a couple of weeks.
I am not the first person to leave a wallet behind or have the wrong card etc when I have purchased petrol and will not be the last.
