Hey guys, regarding the 5% cash back on petrol and groceries, what do they mean by groceries?

Assuming I buy hair wax, shaving cream, shower gel, etc etc that are non-consumable from aeon/tesco/cold storage, does these category of items considered as "groceries" ?

What if I top up my Touch & Go at petrol stations. Will that entitle for cash back too since I swipe the card at the station?
