'Basically between 12-2pm and 5-7pm workers have to be extra careful because that is when gapbusters, who are paid, visit McDonald's restaurants and rate their experience,' Kamran wrote on the site.
'This then goes to the overall store rating and every store manager will do everything to ensure this rating is as positive as possible.'
Kamran goes on to explain that these shoppers always ask for a receipt, meaning that ordinary folk should do the same so that staff may think you're a ‘Gapbuster’ and will do all they can to make sure your food is even better than usual.
Now, who’s up for a trip to Macca’s? But just don’t forget to ask for a receipt!
