After watching the movie from Louis' link, I realised that a lot has improved for the supermarket cashier. Did they have to stand all day? I can't remember that. And then entering all prices by hand and all payments in cash... It also brought back memories of paying with cheques ("betaalkaarten"). I had forgotten that option altogether, probably because I never used those. I always went to the post office for cash. Had to wait there every week in a 20 m long queue on Saturday morning...
