So Twitter is going crazy over the speed of Aldi 's supermarket checkout cashiers.
Social media is full of posts from shoppers sharing their stories of the stress of trying to bag up their items as quickly as they are being scanned - but it appears not many people can keep up!
These Ferraris of the checkout cashier world are even rumoured to be able to go from 0 to 60 (items scanned, that is) in a matter of seconds, or so we've heard.

People have even speculated staff are expected to meet a quota each day of the number of items they get through the till.
But is there any truth to this? The German supermarket chain is, after all, known among retail big-wigs for being super efficient, which is why it can keep its prices so low.
Now, following the barrage of attention its cashiers have generated online, Aldi has explained exactly why its till staff are so speedy.
The supermarket giant said staff members were "encouraged" to be as efficient as possible in their work, which helps to keep the prices low.
They also said they realise some people may need to pack at different speeds and that checkout assistants are trained to alter the rate at which they scan so they match the pace the shopper can go at.
A spokesperson from Aldi told The Sun : “Our employees are trained to operate the checkout at the right pace for each individual person they serve.”
