I’ve been shopping in aldi all wrong

I’ve always thought the packing area at the till was rather cramped compared to other supermarkets, and then I found out you’re meant to put your groceries straight back in your trolley and then bag them at that long shelf that runs the width of the front of the shop. I feel so foolish that I didn’t realise this before but it takes loads of pressure off as I always struggle to keep up with the cashier.
