If a customer hands you two shopping bags, it is a clear indication that she wants her groceries packed in two bags.*
Do not put heavy bags of apples on top of loaves of bread. Instead, you should use the second bag the customer has handed to you.
When a customer hands you a dozen or so ordinary bags, all tidily folded and packed in a chiller bag, do not take all the ordinary bags out of the chiller bag, and ask the customer to unload the chilled items straight away. Chances are that she has her trolley well organised, with all the chilled items together, ready to be unloaded last of all, so that in the meantime, all the other grocery items can be packed in the ordinary bags.
When a customer hands you a dozen or so bags, and asks you to pack just a few items in each bag, so that the bags won’t be too heavy, do not cram each bag as full as possible. I swear, the next time you do this, I will delay paying you until I have repacked all the bags with just a few items in each.
Do not thrust the change into a pile in my hand, and then sigh heavily when I take 15 seconds to put it safely into my purse. My custom pays your wages. I don’t want obsequious service, but a little politeness would be nice, especially when I spend several hundred dollars at your supermarket every week.
I promise that I will continue to smile, to treat you politely, to thank you for doing the work. But FFS, could you please, please, please, treat my groceries (and everyone else’s) with a little respect.
* South Australia has outlawed the use of giveaway plastic shopping bags. We all have to bring our own. We can’t even buy biodegradable bags for 10c each anymore – the bags that supermarkets were selling as biodegradable turn out not to be biodegradable at all. These days, you have to bring your own bags, or buy some more reusable ones, or have some cardboard cartons stashed in the boot of your car, so you can load groceries from your trolley into the boot.
