Kroger review: Gas pump with fuel points

I have used fuel points for many years with no problem, but yesterday the new system cheated me out of my points.

I entered my loyalty number, entered my CC numbers and got the message "you can select between 10-100 cent discount". I decided to select 100 and as soon as I pressed the "1" button the screen changed and told me I would get 10 cents discount. I told the attendant and she helped as we tried again, only to be informed that now I had three cents discount.
