Can you buy food with a Shell Card?

It depends on your account settings, not the card itself, since Shell Card allows product restrictions to be switched on or off per card. If in-store purchases like food and drinks aren’t going through at the pump, that’s almost always a restriction set at account level rather than a card fault, and it’s controlled through the Shell Card business portal by whoever administers your account. This is a common support question for fleet managers, since a driver assuming the card covers a coffee and finding it declined is more often a settings issue than anything wrong with the card.
