when caught in an old-fashioned way of calculating goods bought

It’s annoying to shop in stores where their cash registries don’t have barcode scanners.  It takes time for the cashier to input the prices of all the goods bought by a customer. When you’re in a hurry, it really gets frustrating. In our hometown, there’s this supermarket which is the usual place for shoppers especially sari-sari store owners to shop for their products.  Though the prices are cheap compared to those in big malls, it is also time-consuming waiting in line for your turn because of the slow system in paying.  One time we bought an ice cream, by the time it was our turn to pay, the ice cream was already melted.  We had to replace it with another one from the freezer.  When shopping during peak times such as Christmas or paydays, one really needs to be extra patient with the long queue.  Or else, better shop in big malls where they have barcode scanners so the service is fast.
