nope

this is surcharge, not reload service fee.

Service fee is charged by TnG and normally it's 50 cents and deducted directly from the reload amount.
The amount you received in your TnG card is 50 cents. Check the print out slip for details.

For surcharge up to RM 2 is imposed by the merchant itself.
For your case it will be imposed extra by that Petronas station operator.

Let's say you reload RM 100, amount payable is RM 102 but the amount goes to your card is RM 99.50 only.

explained above.

anything related to surcharge, not to be published.

No surcharge if using cash to reload. Anyway, there are better places to reload TnG.
