I just love to see my favourite cashier at the local grocery store, irrespective of the number of people ahead of me in the lineups. If she is not around then I use the self checkouts. But as soon as I stand in the lineup and she happens to notice me, I get a very lovely wave and a "Hello, how are you". When she starts cashing out my items, we have a wonderful conversation, and she even packs up my grocery items for me. Love that privilege from her. Will be upset if there are no more cashiers like her around, and only self checkouts everywhere.
