1. Come Prepared
2. Shopping List
3. The Checkout
Remember, there are people behind you that want to unpack. Condense your groceries. Use the seperators, that are provided.
If you have a large trolley of groceries, look at anyone behind you with a few items. Let them ahead, if there is room (and they have cash in their hand).
Have your payment method ready. If you have a card with a chip, you can insert it & select cash out (if available). Save time.
There is a surcharge on Credit Cards. ie Paywave etc
Stand away if possible, so the next person can unpack their trolley.
If there appears to be a long line starting behind you, suggest that the cashier 'buzz' another attendant.
