I need your help. There is a self-service gas station with no attendants. You need to pay first and use a credit card to pay 50 euros. But in the end, I only need to fill up 45 euros. Will the remaining money be returned to my card ?

Pre-authorization. Then settle the payment according to the actual consumption.

50 euros pre-authorization, mine is 130 euros, it will be cancelled in 4-5 days, no problem
