Car wash app bug. Local car wash has an iOS/Android app. I used it once & accidentally credited the person in the next wash bay long with $2 (3 minutes). I notified the operators & they gave me a $2 credit to be applied next time I used the service. It worked, the next wash of $2 was fully refunded. But there’s a glitch: any time I choose a $2 wash, the full amount is refunded to me. Other price/time combinations go through as expected & my credit card is charged accordingly.
