SMS fillup bug

[BDC]

Retired car with the same letter as an active car

I have a retired car that I used the letter "s" for when using text message fillups. I recently got another car and decided to use "s" for this car too. I didn't think twice about it, but when I filled up by SMS, it sent the fillup to my retired car instead of my active car.

Is this a bug or should I just find another letter to use?

Thanks! (BTW text fillups are great for those of us who don't have smartphones!)
