However, you will not be able to use the fleet card for payment at a Shell petrol station. If you have forgotten to use the fleet card at a Shell petrol station, please make your payment at the cashier first. Remember to upload the proof of receipt at the end of your trip for reimbursement (via e-wallet).
However, these workarounds are only meant to be used for extenuating circumstances. You may be denied claims if you regularly use this for indirect benefits.
