Can I ask a question? When I returned the car in Switzerland, at a self-service petrol station, I used my credit card to top up a total of 4 liters of fuel, but 150 francs were charged to my credit card ?

The general process is to swipe the card, enter the password, select the fuel nozzle number, then deduct 150 Swiss francs for pre-authorization. After filling up the tank, swipe the card and enter the password again to confirm the actual amount of fuel added. The machine will print a receipt, and the pre-authorized 150 will be automatically refunded.
