Some of the pros around here are not very good and take longer than I do, but the Aldi ones are usually fast with those giant barcodes! The last one, however, charged me for two melons but I didn't have any, removed one, but not the 2nd so I had to go back over. My data points and the workmanship around here show sometimes quicker than me, but not if a line for them and none for diy.
